as a battle rager berserker and then tell me deathblow is overpowered. Or for instance lets say there are imperials sitting on eastern road with centurions and a gank. Or you walk through galadon and get summoned into the locked room. Air shifter scions/vindicators. so on and so on and so on.

Sure db is powerful as hell nobody is disputing that. The justification that everyone keeps saying is that there are so many weaknesses going on in a ragers life that they get such big bonuses to counteract these. If you choose not to capitalize on their several weaknesses then your just not playing the game very well.
