warlocks got that wing flap knock back
hunters and that bomb or the rhino pet
shamans have theirs (forgot what is called)
I think it would be amazing if warriors got a push back only difference being it would be single target. (unlike all of the above which affect everything in your path.) warrior's push pack would only affect your current target! and they could make it work when you are equipped with a two hander sword, or mace in both hands. so that it looks like you just batted an enemy to kingdom come. or maybe make it work while you are equipped with a shield so it looks like you shield slammed someone all the way to vanilla! I dont know I though it would be cool.
