Well, if you think about it, with the 10 second duration, depending where you are at in your rotation, you'd be choosing between DPS or helping to heal off your Living Dead. You have to consider GCD timers. Don't think it'd be hard to let it ride for the whole duration, keeping that in mind. Other times you could take it off, almost by yourself, if you were able to have your combo line up right. It'd take some thought. I'm sure SCHs and ASTs would appreciate the help too, cause they ain't letting you ride the invuln for the full 10 seconds, that's for sure.
