But the point is to make talents atteactive choices, not null. They're letting druids cast heals in bear form for crying out loud. I really think the time for such limitations is past when it comes to these talented abilities. Divine Star is supposed to compete with either a free Mind Blast, or Archangel, and the only way that's happening is not breaking Shadowform
. The same with Bulwark/Final Prayer vs Desperate Prayer. Desperate Prayer has to be attractive as an option, and for that to work as a talented ability, for any reason a Shadow Priest wants this, it has to not break Shadowform. That said, Flash Heal, Divine Hymn, Smite, et al... i expect these to continue tearing you kicking and screaming from the shadows faster than parents do to emo teens on picture day. But not for these.
As for Levitate, I can see it changing. They want to remove "clutter and useless spells", but specifically left this one in, and talented no less. 25% could potentially be downplayed by breaking on Damage... Except this is even more limited because it's self-only. So yeah, Levitate has to be changing.
