Watch out Warlocks, the nerf bat is headed your way! Straight from Blizzard’s mouth:

“We will be implementing a hotfix this evening that temporarily removes the Warlock Imp?s spell damage coefficient as it was performing far in excess of our intention. This will remove any spell damage bonuses from improving the Imp?s attacks. We are currently on schedule to be implementing the correct values with the next patch. While we are able to effectively block the spell damage bonus with a hotfix it will require a client side patch to input the intended spell damage bonus the Imp is receiving.”
