Got 41 tankassasin , takes a while to kill, a dps assasin will kill my tank asassin in a few secs, luckky crits, I dunno!
Also got 47 powertech pyro, takes long time to kill, but both will kill sage/merc eventually. Scoundrels just stun them to death! Apart form tank assassin , marauder kills every alt before I can blink! My 27 healing scoundrel is at 50% health seconds after even a level 10 newbie maruader attacks! STun maruader twice, then he walks up to me or leaps and I got nothing to do but revive within few secs:(
