Playing on EU I would have say....
Tav 91st: Like dude was way smart when I was in the spartans and we 1v1 them. He was extremely smart when it came to handling anything.
Donald - 92nd- talk about a winner. Littlefield learned alot from this guy to make the 92nd NA side just as good. Hands down made one of the best overall regiments in this game to date.
Pieter 17e- dudes my homie I love him. One of the best leaders I have ever had.
NA side of things
Comp shit:
Tico/Breaches: Yeah they had a pretty good regiment overall but they were pretty good when it came to tactics as well.
Karth/Offizer: Ray (offizer) is probably one of the most underrated leaders ever. Man learned from Hekko. And plus Karth was pretty good to. Yeah you kids can quote me on that shit.
Millander/MackCW: Dudes were the forefathers of the NA comp scene gotta give credit to where credit is due.
Asianp/company: AsianP was always involved in the 1v1 scene based on his actions he clearly wanted the comp scene to grow. He's up there with Millander and them in my book.
