If we have Foe Requiem (or The Balance or Technical Step) as a damage buff for the raid during a specific timing window, then any job who can line up their own buffs or cooldowns during it that window will become stronger than others. The meta might not be 2 minutes anymore, but an 80 second, or 45 second, or 72 second, or 90 second, or whatever-the-heck-second meta isn't any better. If some jobs don't fit that mold and are worse-off, then we'd actually somehow manage to make a worse version of the 2 minute meta.
You could argue this is a slippery slope fallacy but given the game's design has already been falling down that slope for a decade I think it's a justifiable concern.
