Only Electro Brains I think. That zombie seems a bit too strong anyways currently, not as crazy as Rose on the plants' side but enough to be the favorite pick on the zombies' side apparently.
Brains and Rose also make some maps "unplayable". When a map has an open wide field the match turns into a deathmatch even if you're supposed to invade/defend gardens/graves. It's just two walls of weapons firing at each other (biggest issue on that northern ice level where there is just one way to the first garden). It's nice that this game adds some variety to the maps but the multiple narrow and cornered paths that you had to protect/invade on the first game did a better job at keeping the matches interesting. Maybe this is going to change because Rose got tweaked now and maybe Brains will as well but if not, this should be addressed as well. It's no fun to play gardens and graveyards when all players can only shoot at a wall of enemies. Doesn't even matter if I'm on the winning or losing side. It's just like the game itself describes the backyard and the plants and zombies being front to front: it's unwinnable and you're stuck with two lines of players shooting at each other which turns it into a deathmatch type of game.
