Also, aborting that Pyroblast is always delightful.
But remember, this is purely a PvP talent. Of course, a few mobs will be susceptible to this, but mostly this won't be more than a PvP shot. Damn good PvP shot, but still, only for PvP.
Edit:
I do know it affects other skills as well. I was hit with this in Arathi Valley once, and most of my actionbar went red. I can't really confirm what skills it affects, because I was dead soon after.
