This ability really needs to be something we obtain at a far lower level. As a level 80 ability it really, really sucks.
Hell, to be fair, it sucks period. 10 minute cooldown for yet another purgable Priest ability, and wonderfully enough, a third Priest CC type Undead can go immune to. Will be lovely to pop our ten minute panic button and have a UD Rogue pop a 3 minute WOTF and just keep slamming us with a good ol' combat log full of immune.
Of course, I assume WOTF will probably eat a nerf in the Racial review next week (and hopefully Perception as well). But racial whining aside, something like this would really fit better at level 20 or 30, something a person could use while leveling. And of course with a shorter cooldown, 10 minutes is just... This is on par with Heroism to them?
