Very simple The wipe mechanic on GM and probably Ultimate is way too short. On a fireteam of 3 with one bane modifier and 3 boons we finished it with 10 seconds left while actively rushing absolutely everything. If we had made the tiniest mistake at any point, we would've just fail. This needs fixing, because otherwise you can't do this pinnacle unless you know it perfectly and make absolutely no mistakes. This was on normal difficulty with a power level of 419 on a 420 activity.
