To put it simply he did the most with the least. His regiment wasn't the greatest in the scene to start with but had been highly competitive in the scene always under Karth's leadership and even dominant at points up until Karth's departure. While his regiment did have some melee players it paled in comparison to most other competitive regiments. Karth made use of his regiments shooting in a way nobody has replicated since, with extreme IQ of shooting angles, timing, and maneuverability in what was most of the time a huge line. He was able to put together a tight cohesion in a regiment that lasted strong through out the years while the others faded and when returned seemed to have lost their touch. Karth's consistency and dominance over the scene in a highly competitive time earns him the top big brain spot on this list.
While it was known that Breaches was a decent bit better of a leader than Tico, it's hard not to give credit to them as a duo for their complete destruction of the scene in the early days of competitive NW. These guys put together a regiment so skilled and bred straight from scratch, the likes of which hadn't been seen yet in NA's scene ever. Tico playing an integral role in the regiment's development as the Colonel, while Breaches lead the charges in linebattles. While they were active the two were unmatched as leaders for a long period of time. They made pretty damn good use of the volley and charge as their melee was as dominant as their stacked officer corps. Having this advantage in melee is always nice as a leader and is no fault of the 12th's as they trained them to be that good, but it also takes away from the amount of effort one may need to put into leading at certain points. After the 12th it didn't really feel like they ever had that sauce, more so probably because they were just playing to have fun and not sweat nearly as hard.
I honestly can't speak too much on AsianP's older days, but back then he formed and developed the 3eVolt to later become an all-time hall of fame regiment. He also found success later with the 79th, 58e/91st and later 3eVolt reforms. It seemed he taught Grimsight how to lead as well who is regarded by most as one of NW's greatest leaders so I suppose you could say he is a leading pioneer. He had really good fundamental leading and timing of his shots that blended well into melee engagements, he also good use of maneuvering around the map. He wasn't the most active during his 58e/91st days but when he was on it was what made the difference for the 58e to dominate other regiments. His leading when he came back was still pretty good and above most other leaders which led to his success particularly with the newer 3eVolt over the LG. So yeah extremely well rounded player and leader, definitely deserves this spot. Actually one negative thing is he sometimes chokes.. nothing too bad though.
Grimsight pioneered some tactics back in the day that people now use all the time, such as the "reverse column". I mean I don't actually know if that's true but he used it really well in linebattles. He was usually best leading around his big ass line where he'd reverse and bait your shots then reverse back, get a better angle and plop his line down for a big ol' shooting engagement followed by a charge. It's pretty frustrating to deal with someone who is just constantly moving and is hard to get any shots off on. Grim led the 3eVolt to it's peak during 2013/2014 where he was able to be one of the largest and most competitive regiments in the game and were the only ones able to compete with the 12th on a close level. A real bright individual.
Led a pretty large regiment back in the peak 71st days and managed to compete with Karth and win an NWL title. He was pretty fast with his reverse and used a simple but deadly leading style to come out as one of the best regiments in that era. Though Cheesey didn't necessarily find huge success until he had a huge cast of melee players to crutch on when he needed it, he shouldn't be discredited that much. He kept winning and led with the exact style that one should with a deadly melee crew. This unfortunately does kind of takes away from his *actual* leading skill so it notches him down slightly though he was still a very solid and consistent leader and one of the all time best.
Zorkoth was actually a pretty decent line leader and lead the most out of anyone else other than Tico and Breaches. His leading style I am not very familiar with but I'm told he made a big impact for the 12th and stepped up when it was needed against big names, a true legend of the golden era, if you don't know now you know.
Ody was pretty underrated back in his day just because of how hated he was as a person. He actually led quite a disciplined and tight crew though and used his swivel tactics to his advantage, when paired with a few key melee players like he had after the 71st disappeared, he can prove to be quite difficult to deal with. Even without them his leading was always a pain in the ass to deal with and his regiment were like above average pubs that he'd trained so he was decent for sure, one of the most underrated/underappreciated leaders of all time.
The 6te was/is quite the motley crew, but Irish put it together and managed to dominate the latter half of the NW 1v1 era. He uses his shots with great effectiveness and manages to keep a solid distance between the regiments. What I mean by that is he'll manuever to safe spots and advance to avoid shots really well and then reverse and reform and all that pretty line stuff. Pretty similar to Knight of St John's leading style actually, though he did have some pretty good melee carries at times to rely on. But yeah he's an extremely stubborn leader and with this won S8 and came 2nd in S9 of NWL with a lot of it being leadership.
Alexander's regiments namely the 7y and 5th dominated the underground scene while they were active. They didn't really have the player base to compete with a lot of these high skilled regiments but it was mostly through Alexander's leadership and cohesion as a unit that led them to be able to compete with these regiments as well as keep dominating the "league 2" scene. Alexander managed to form a larger group with more experienced players in what would be his pinnacle in the 75th. He managed to lead his regiment to a league title which is an impressive feat no matter the time period, though it was against a practically fallen apart 18th squad. His workhorse attitude and commitment led them to that title and few can deny him that TNWL win. Unfortunately Alexander didn't find much success in NW after this as his future attempts at putting together a solid regiment failed and he was basically squashed out of the scene.
Also an underrated leader, Stox excelled at leading massive lines and maneuvering them about. In the 54th's peak they were competing heavily with the 63e, 3eVolt, and 71st. Stox had a fucking stacked officer core as well that was utilized well including names like ByeBye, Locust, Balthazar, Decimos etc. Stox had an extremely disciplined unit and had a massive regiment so they had a lot of pubs but also SOME decent melee players. I think they lacked in the melee department for sure but with Stox's leading and use of volleys they were one of the top dogs back in the day. They kinda did fall off though in their later reforms struggling against regiments like the Nr37. The 12te was pretty decent as well but never peaked to the level of size and skill that the original 54th had.
Knight of St John
Knight of St John was quite an effective leader despite the skill disparity his regiment would have in melee engagements. The PSG was a coordinated regiment but lacked individual skill, to make up for this he made use of tight left/right advances and reform columns to evade and bait the other regiments shots, then would try to find a good range to pick the other regiment apart in shooting before finishing them in a melee engagement where they had the numbers advantage. He was quite difficult to deal with as a leader because of his meticulous and stubborn leading style. He was able to earn most of his regiment's victories as well as a L2 victory with the PSG and another leading the AEF to their title. He had some close matches with higher tier regiments and I would consider him as one of those "what if he lead this regiment of players" leaders for sure.
