What's the deal with Marked shot? Sometimes, now more often then not Marked shot wont work saying "invalid target". It does it a-lot when killing trash packs and I assume it because the target I was targeting when I cast sidewinder died before I can get off marked shot.
Last night though, it did it during the initial Mythic Nythandras pull before anyone can get mind controlled. So my theory on multi target triggering the bug went out the window. Popped my 1200 gold potion True shot and POW I can't cast marked-shot completely screwing up the rotation and my dps. Does Blizz know about this bug?
