I've been searching DPS improvement for a while now, and one aspect has me confused. To recast the DoT, or use Fel Flame. I just installed AffDots addon to give me a gauge of the power of my dots, but I'm not sure if I should refresh with fel flame or a fresh cast. I know this probably makes me come across as an idiot, but I'd rather ask, get the answer and be ridiculed than not know and do less than I'm capable of. Thanks in advance.
