I agree with Jpec, in general, it shouldn't be a requirement to stance dance.

If you dig into it, it always depends on a couple of things, the encounter and your healers. What the community seems to miss quite a bit, is it isn't always about whether you can survive in SwO, it's also how much work you're trading between your dps and your healer's. Remember those ramparts you're using? yea well ShO is equivalent to 100% rampart uptime.

If your healer says okay do this in SwO, I'll heal you more and do dmg no problem, sure go for it. All I'm saying, is that the stance dance thing isn't black and white, unlike for example... should a bard dps with WM turned on.
