So what are you doing when you get bitten, and you have to wait for SW:P to fall off. From what I have seen so far is that I have to wait for it completly fall off. Refreshing it with Mind Flay, or just recasting it does not increase the ticks for the buff.
Besides keeping the other dots up and MB on cd, do I just go and spam smite for a few casts??? Or do I just stand around and wand?
