Fending vs. Slaying accessories at this point in the game

[Perzeval]

yes but whats stronger about 100-200 extra tank dps for going full str or the extra 500-600 extra healer DPS when they don't have to spend the entire time keeping your low health bar from going to 0...

Strangely enough, my healers never had any problems keeping me alive while doing DPS on their own (250 Scholar DPS pre-echo T13). Maybe you are just overestimating the impact of tank HP on a healer's potential to do DPS? Giving up 500 extra Healer DPS because the tank has 3k HP less... come on, no one is going to believe your claim. The healer's DPS is not crippled by the tank having less HP, it gets crippled because people (including tanks) screw up mechanics and eat more damage than the healer anticipated.

And no, my healers do NOT have to pay more attention to me just because I'm not running around with a 22k full vit warrior build. I know when tank busters are coming, I know when there are periods of sustained heavy damage, I use a apprioriate cooldown rotation for the fight and if the shit hits the fan somehow, I still have holmgang and Equilibrium.

I'm not a hardcore STR fanatic either. I would definitely use fending/melded gear when the fight is new and I'm maintanking, but not when it's on farm status and I'm offtanking.
