I'm at or near my focus cap AND serpent sting is about to fall off.
Do I:
1) Cast Cobra to add duration to my Serpent Sting about to fall off - knowing well that the focus gained from it will be wasted because I am at or near the focus cap.
or
2) Expend the focus in Arcane shots to avoid focus being wasted - consequently letting serpent sting have to fall off and reapply it.
Please help me with this question it is perplexing me!
