Sylvanas’s new pinnacle quest can be stacked off of mercenaries.
Which means you can repeatedly let the camp reset over and over to finish the entire quest very quickly. Once your level 4 and can stun camps again, you can keep a melee merc in perma stun and reset healing at the same time quite easily to accelerate this even further.
Imo, a good chunk of stacks should be earned apon capturing a camp so that your encouraged to actually capture them instead of abusing camp resetting.
