Right now I'm a STA/INT Monk, in theory built for tanking. I used to be STR/STA, but switched things around when I noticed just how many extra hitpoints I could get from using certain weapons.
But recently I was thinking about how our Def Stance dictates that we will ALWAYS parry 12.5% of attacks against us no matter what, including epics. Other boosts to parry, defense, deflection, and dodge will raise our avoidance, but that only helps a little bit against high end mobs, if at all.
BUT, what about the riposte bonus from the KoS STR Brawler line? Pre-EoF-Revamp, at least, 8 points in that achievement added a flat 5% onto your avoidance. Is THAT achievement influenced by mob level, or is it a straight-out chance to riposte? If so, wouldn't that give us an effective avoidance basement of 17.5%?
Makes me think that a full extra 5% avoidance that works on mobs of all difficulty would be better than the stats I get from my weapon.
