Serious question, do you guys find sometimes it knocks back like 5 yds, but other times it can knock back a fair distance? And do the knockbacks stack? As in, if I hit the guy with 4 knockbacks (all my shammies standing in the same spot), will he go back even further. It seems to be like that, a knockback will hit the guy when he is like 4 yds flying away and will knock him on even further.
