Pop cap wants to know the 3 variants to buff/nerf via twitter (link inside)

Nerf: Zombies. They win multiplayer matches way more than half the time.

1. Superbrainz: turbo twister is ridiculously overpowered; they shouldn't be able to do all of damage AND have all of that armor at the same time
2. Scientists: it's unbalanced that Zombies have healers with 1: warp in/warp-out and 2: a very powerful close range attack while Sunflower has no comparable offensive ability, particularly since GW2 maps don't have as much opportunity for long range attacks
3. Imps: Between gravity grenade and their increased health they're super, super annoying

Buff: Plants, to parity with Zombies in multiplayer

1. Rose: got hit too hard with the nerf stick and now isn't very useful at all
2. Cactus: less effective than in GW1
3. Chomper: way less effective than in GW1
