Yeah, I knew I was getting the name wrong, but I figured most people knew what I was referring to. Final Wrath is what I meant.
I agree the BH is only useful on fights where you use SOI, but for me, that's all fights. DivProt I keep in MOST times, the few that I swap are for Lei Shi, HC protectors, and used to do it for HC feng. Expecting it to see similar use (as in, swapping) in 5.2 given the "thunder-theme".
In terms of your last point: Its a survival increase on most ANY fight (minus Lei Shi) given that, by and large, the majority of damage that threatens a tank is going to be physical. So having a 40ish sec CD barkskin is pretty damn useful. But, if you're pushing rankings, you most likely have the content on farm and can easily afford to give it up in favor of a DPS glpyh. However, I'd be curious to see how much overall damage a DPS glyph (which is NOT focused shield or alabaster shield, as I'm considering those "mandatory" for the sake of this thread) like DJ or Final Wrath really contributes.
DJ is a 20% increase on Judgement (which doesn't exactly tickle at high vengeance), but requires certain situations to be present and the player to use/abuse those. Taking Protectors, for example, you'd have to judge a non-kill target to get a 20% bigger judge on the kill target. Cool, bigger judge. Problem is that it's less USEFUL damage on the kill target than just judging x2 on him to begin with.
Final Wrath is undoubtedly a DPS increase, but it comes only at the last 20% of the fight, which usually lasts for far less than 20% of the encounter when you factor in how many fights require heroism/burn at the end, and execute classes.
Not trying to say you don't have a point when the issue is pushing WOL rankings, but I'm not (personally) going to forego my base survival requirements to do so. Unless it's farm, in which case nothing matters anyway
