Tanks, please use strength gear.. :(

[Shyle]

I have 2 sets, a STR set (which I consider my primary set) and a vit set (i'm at 21k in defiance with it). As for dungeons, I have yet to have any issue doing fast runs with big pulls in my str set in DF/EX. There are times it can get hairy due to maybe the healer not paying attention or maybe I just ran too far ahead out of range and had to use a few CD's, but in all I'm comfortable with 16.8k hp in str set. In Fractal and Neverreap, I only have defiance on during the first combo for the second boss, I swap to deliverance since the damage is all avoidable (and auto attacks are minimal at best).

It's all about how comfortable you are as a tank in the encounter. If you're learning, use vit, I would assume if you're in progression (savage), Vit or a mix would probably be preferred. I just had a "discussion" with a new warrior who said it's not their job to do damage, but "survive", I agree with the survival part, but I think if you're running into basic dungeons with 20k hp, it seems wasted to me. Of course this tank also didn't have provoke, or monk past lv. 11. and only did butchers block combo.
