So instead of being on a duration...why not just hold your stacks? GNB can do it.

I hope you know that 2 minute raid buff and decreasing Req effectiveness is also restrictive design, and isn't very engaging. And no one likes Shinten. At all.

But that's the problem. Overreliance on raid buffs and rDPS.

And if you want to make PLD a rDPS Tank then it's damage in relation to the other Tanks will always be low.

But then again maybe you have the dev perspective where everything in PvE is a fixed rotation, super rigid and plays with no brain restrictive kits with no room for optimization.

I for one dislike raid buffs under a burst window because there isn't much to improve on other then hit all your buttons before going back into your 1-2-3-sometimes 4 for 2 minutes again. Sounds pretty boring to me.
