for a previous poster, it doesnt matter if you're stunned if you're a raid tank... you shouldnt be moving around in the first place unless you want to wipe your entire raid party.
You mean rooted right? Cuz stunned also makes it so you can't even attack, use combat abilities, or taunt or whatnot (unless it's something that can be used even while stunned, like our single taunt). A raid tank will need to still keep aggro, so root doesnt matter.. stunned does matter.
Our taunts can still work while stunned, and that's 30 secs of lowered damage on you.
That's one taunt.. our single taunt. We will lose aggro from groups in a flash if there's any AoE nukers. So basically we can get 30 seconds of extra mitigation, but then are stuck with a single taunt for aggro for 2.5 minutes... I'd end up cancelling that.
Remember, it costs power for that 30 seconds. If we are talking about a raid situation, I'm not sure if the power is worth the little bit extra it's gonna give.
I still see it as an emergency use thing. I'd use it if I was pulling and got nailed while my buffs were down due to out of range issues, and the healers needed time to play catch up on the heals. Since that usually doesn't take too long, 30 seconds for that situation is fine.
That's a rather specific situation though.. won't happen every time.
