I noticed that the new level 15 talent Soul Leech heals us for 25% of the damage done of Shadow Bolt, Incinerate and Malefic Grasp.
Is this a new spell, if so, will it be considered as affliction's spam button in PvE (Incin for Destro, SB for Demo and MG for Affl)?
Edit: Also noticed it at Illidan's Guille.
