Yeah the buff, FFXIV wise is outrageous lol. Perhaps something along the lines of 5-10% and of course the cooldown having to be substantial. Like 2 minutes.

However, I’d defiantly have the buff last at least 30 sec or even a minute.

Bc RDM is a DPS, so the last thing they’d need is mid boss fight, during a Combo being asked “hey where’s my haste?”
