well

DW - there's one nice gimmick - 1 PU, controlling of that is the important part of the game. It requires also movement skill. (i really like that factor)

Semi - i've played there 100000 times, so there will be no difference if I play one more time.

Marshland - fun level where movement skill is also helpful, there's no reason to remove it.

NA, MS - the routes to bases are so tight, there are also a few campspots. In MS the situation is kinda better because of the flying carrots. Thought I don't dislike these levels, I wouldn't place them in jj2wc.

zaitox, sbv2 - imo these levels are too campy, zaitox - one person camps bottom entrance, second the base and there's an easy rush, ins bv2 it's so easy to rts.

superconductor - the people who say that it's too small probably haven't played any 3v3 here.

neither have I, lol

je - it might be fun thought I've always thought that the carrot spawns too fast

gw - too horizontal-based and linear
