It's just hilarious that Blizz can't fix this. For Melee it's simply not acceptable (for ranged as well probably). The mobs you are fight are RIGHT IN FRONT OF you and you tab and tab and tab and tab and none of them is targeted. Some other mobs in a trash group 40 yards away are. So when you finally found your mouse cursor to manually select something mobs are dead. As a Fury whose dps highly depends on burst AOE and Execute its just a giant clusterfuck if you dish out zero damage before the pack is down because you can't target anything.
THIS CANT BE THAT HARD TO FIX?!?!! I can't remember this problem in WoD, at least not that bad!
