Simple enough; the Nerfstorm was made because of T1/2s complainin' that the game was too hard, and now all we have are T3s complainin' that the game is too easy. No one's ever gunna be happy about this, so why not comprimise?

T1: Leave the nerfs the way they are; everything's extra-easy, no danger. Zombies are slow, don't track. Wolvers don't track etc etc
T3: Undo the nerfs; Zombies and wolvers track again, they hit faster, everythin's scary the way it was again, yippee.
T2: Come up with some agreeable midway; have zombies track, but still slowly, or have them attack faster, but not track etc.

Just the way it is with everything else in the game that actually gets scarier versions as they go up tiers, such as Jellies. The things that got changed can easily just be different difficulties across all tiers, letting people work their way up from slow, boring, easy mobs into fast, ninja, evil tracky mobs on T3 again.

Everybody wins.

*cough* Except the T3s who bought their way up there and refuse to ask for advice or help in the game, but it's not as if they really get a fair say in the matter if they refuse to play the game properly by practicing and getting better like everyone else anwyays *cough*
