When spirit bomb first was relevant I was very annoyed, because the ability slows gameplay down in many cases. Also, perhaps even more important there is nearly no visual feedback when using it. Comparing it to e.g. Eye Beam, Blade Dance or Demonic Leap, it feels like I'm not even using an ability (from a visual feesback point of view).
It made me stop playing the specc altogether and I was always waiting for that talent to become irrelevant again, but its just not happening.
That talent basically is the face of the whole spec and it drives me nuts.
How do you feel about it?
