@EA_HighCommand Thank you for taking care of this issue.
In your test, did you try in auto x4 ? With high speed Revan team (like 120 speed on all toons) ?
Nest is usually modded with 100-110% tenacity, 60k protection in total and around 600 additional physical damage.
At first, Nest can't kill the other toons, you are right. However, with the buffs, the critical damage is increasing more and more, and from the feedback I have, after 3 or 4 minutes, Nest starts to hit for around 100k. It just needs time to build up, and needs the Revan team to get as many turn as possible so the critical damage from the passive gets very high.
Hope this helps to reproduce the behaviour. I feel that this is not the way it should work, but if you think otherwise, let us know 🙂
