Look, I understand people may not have the experience in games to instantly realize it's a gauntlet that requires precise targeting of the droids first and I can understand the clueless starting of the event because it happened to me as well. I'm getting kind of burnt on out on the whole bugged/broken/hard/*** forum posts plaguing my threads.
Holding right click to aim(move camera) gun at bugs is not a difficult concept after 1-4 attempts. yes, droids do a **** ton of damage.. kill them first.. hell, the first droid can be killed before it attacks no bugs should be getting near you since guns do AoE AND penetrating shots knockbacks happen 24/7 in maze, plan accordingly
I have to say I loved this instance, not because I "didn't have problems" but because I enjoyed the thoughtful side and mechanics that make it "difficult."
