I don't think the sky is falling for warrior like some people on the general forums would have everyone believe, but it sure does need some QoL adjustments. If for nothing else, than just reverting back to swapping stances not costing resource.
I know someone did the math, and regarding potency loss, switching even with losing gauge is on paper not a significant loss compared to the other tank classes on a strictly GCD basis, but when you consider how much it throws off overall rotation throughout a fight, it's silly.
For optimal gameplay, it very much involves both spending gauge on Fell Cleave to line up your Infuriates for the burst as well as having relatively specific gauge numbers at certain points so you can line up burst windows with your/your party's CDs. Losing out just feels really bad and quite the opposite of fluid gameplay. That and getting beast gauge in multiples of other than 10 is insulting. What am I going to do with 3 beast gauge?
DRK so far has been easier...I guess? I haven't really pushed numbers and am not as familiar with priorities, but I finished the final quest right before raid night with my static and was able to pull a 92nd percentile parse. I find myself looking at the hotbars a lot more, but then again I think it's just unfamiliarity with the class. It does feel like there is less need for the stars to align to fit burst phases in however.
Right now the clear winner seems to be PLD, both in terms of utility and overall DPS.
The one thing I have to hand to SE is this time, the tank numbers are all pretty close. PLD does seem to lose the least while in tank stance however, and if SE is really concerned with keeping people in their intended stance - they need to not only concern themselves with making content hard enough that needs it, but make the actual tank stance not feel like a punishment when I have to use it.
Sorry for the rant. I love tanking and the overall tanking meta, and I get on tangents.
