Since the hotfix I think they lowered the amount of comets you get in total. We often had 3 spawn between nuclear inferno, and now its never more than 2. Has anyone tried Twins after the hotfix? I think the healing requirement went up by some, since you cant just get stacks down on comets permanently.
You will basically get 1 comet to lower stacks, and 1 comet to hide behind, and thats it.
