The cooldown reset on A8s is unbearable

[Nekodar]

Running a8 again, the 120 seconds every perfect balance if someone messes a pentacle is destroying everyones mood. Its horrible :<

Sounds like a good motivator to not screw up there...
From my perspective it sounds like your group have the wrong mindset going into the fight. Thinking "if we only had cooldown reset..." instead of "we need to get better at handling this. what can we do?".

Again from my perspective, cooldown reset would cause quicker burnout and less progress due to people thinking "we'll just wipe and try again" without stopping to think about what went wrong and how to do it better next time.
