The only time I could see it being "wrong" is if you were using it in a dungeon between pulls, considering it uses up a considerable amount of MP and Flash is how you hold AoE aggro. But in raids if your TP starts getting low, I don't think popping out a Clemency here or there on the MT/yourself or a DPS who ate an AoE would be a bad thing. Heck, since removing WHM's Stoneskin and Protect traits, (if you really wanted to) you could actually go a bit further and help the healers out by Protecting anyone who happens to die.

I feel tempted to go level Paladin now and be the best White Paladin Mage ever.
