This will never happen. classes with a healing spec are not supposed to have an execution ability.
Therein lays the problem. The most squishes of classes not allowed having one huge attack solely because they can heal? Please, thatís ridiculous. Iíve never played in an MMO where that was the case. What BW has done to the Inquisitor/Consular classes is egregious in that regard. Thundering Blast should have the highest hitting damage capacity in the game based on the weakness of the Sorcerer AC. But, we cannot have that, LOLSmashers Inc., will have a conniption fit, and wet themselves QQing all over the boards because their Smash/Sweeps cannot do the same damage. Don't want to upset their delicate mental balance...you know how vain they are.
