Well, I have only been back like 2 weeks, but thus far I dont see an issue with the number of competitive regiments, they are still around, just different rosters as usual. I would say in order to drive the competitive scene forward a notch, maybe partner with a famous twitch streamer or youtuber to commentate competitive matches, create an overall competitive ladder (its easy to custom create a page like that, I am sure one of you guys has a coding nerd in your reg), and have a committee oversee that ladder weekly, to ensure up to date statistics, which can include regiment wins/losses, and maybe even player data (if regiment leaders can submit player data most of this would be seamless, also if any way to track k/d during linebattles using a script). And yes, prize money should be involved at some point if you really want to turn it up a notch, you can get some sponsors to offer a reward, maybe steam gifts or actual $, but this is what I was going to do a while back.
Clean up the shit. (pardon my language) but the amount of shitposting and trolls since I was gone increased 10 fold, its pretty amazing. People also need to stop reg hopping every few months, I think the new league rule will be quite effective with stopping that on the competitive side.
Also for those calling 63e biggest NA and stealing all members, that is not the case. In the beginning, a lot of them watched either diplex's or speirstheamazing's 63e videos and were instantly attracted to us, regardless if they used to play on our siege server or not, they knew what type of community we had prior to that. And on our siege server, it was strict but we tried to make it as fun as possible (unfortunately it died since I was gone), but again we were not the first regiment to use that monopoly strategy. I also was already acquainted with several youtubers who wanted to play with us, thats not my fault or the regiment's, in fact it probably did even more to get those audiences into NW, probably hundreds of new players.
Retention rate in this game is one thing that will always be a struggle, and to fix that you need to have a community united and structured in a way that makes it immediately more enjoyable and immersive for a new player.
Just my thoughts, bash away if you like, but just from what I am seeing since back (and personally I dont have time to do whatever I said anymore which is why its all out there in the open)
