The only problem i have with the whole "let pets have aftermath" idea

Aftermath is kinda sucky. It doesn't proc enough to justify itself. And half the time the duration is wasted changing from mob to mob.

Don't get me wrong, Pets getting aftermath would be cool. But if thats the only change they made to cloudsplitter it would still suck.

It needs a serious damage boost to make it viable. It should easily be twice as strong as other normal Magic WS's

Side Note:
Personally i think aftermath should be based on a swing counter not a duration. I.E. 100% tp = 10 swings with a chance to deal double dmg ect ect. And the counter should overwrite (not stack) Ex. I have 3 swings left but i use WS at 100% and now im back at 10 swing counters (insted of still being at 3 or stacking to 13).
