It is not that people hate AA, it is that people hate the AA in Reach, and for good reason. Armor Lock, wtf is up with that?! You can destroy a vehicle by going into it and kill enemies with it. Also, Evade? C'mon now that was just OP because of how fast you could move. Invisible was dumb, Sprint was actually cool, and jetpack was useless usually. That is why most people hate the AA, they are either OP or just plain useless. The ones in Halo 4 look to be good though, nicely balanced and they fit into the game. I am very excited for it.
