I don't think it's really overtuned, but for pugs the Cycles at the end are probably a bit ridiculous with how easily they can impact your dps (and so the clear). It's the hardest mechanic to dodge in the fight and it doesn't show up until the very end, so getting to the point where you can actually practice it feels like it takes forever. Thankfully my static is almost at the point where we can skip the cycles entirely, because I don't want to see them anymore.

Doing a special mechanic at the end of the fight definitely isn't a unique thing to E2S, but I feel like most don't have the same ramp-up in attention required compared to the rest of the fight.
