But...aren't buffs canceled when you die?
The request is asking that cooldown timers be reset on wipe. When you die, your buffs expire, but the cooldown remains intact. Trials and fights like A8 don't let you release until the party is out of combat, so resetting the cooldown timer on release can't be used to double up, nor let players die just to get their buffs back. In fact, with boss lockouts, I don't see how resetting cooldowns on release in instanced content could be exploited.
