As a 'spastic but finely tuned' Zombies melee'er, that permanent aim assist made the higher rounds extremely frustrating, as well as made those galvaknuckles the most useless weapon in the game. (lunges every time)
My friends and I have stopped playing as a result. So having gone from playing every day to not being able to play well at all, you can imagine how happy I am about it.
From what I understand that terrible aim assist has been hotfixed out of multiplayer for the time being, but it's still in zombies and quite honestly, for as easy and as crucial a fix for zombies wiimoters that this would be.. it's day 15 now, I'm feeling ignored and we're starting to lose patience.
