Buff-stacking warps the design space around it like a neutron star. It means every job has to have stuff to unload in the important buff-stack window, so every job becomes a builder-spender or cooldown-monger or both, with no room for any other design like sustained-DPS. That's beyond tedious.

Not only that, but since the buffs are multiplicative and ubiquitous, each one has to be so weak individually that it blows playing a buff-intensive job in light-party content -- you need a parser and a microscope to see the difference a 3% buff is making in a dungeon. How about that -- the buff meta is ruining the buff jobs. Golf claps all around.

I'd love to see the buff-stacking meta killed and the job devs twist in the wind for a while until they come up with some more diverse designs.
