So does every hate new PLD now?

[Shurrikhan]

If two tanks have the same dps(t) curves, they have the same average rDPS. You obviously cannot assume the reverse, but that's not the point here.

It damn well should be the point as long as you're still pointing at rDPS and going "rDPS parity? Then I guess they contribute equally." You keep pointing at similar average rDPS and trying to infer equivalent damage profiles from it. It doesn't mean that. At all.

If they have the same rDPS in the same fight length, they same personal damage dealt within the same length of time, but that says nothing for when, precisely, they dealt damage, nor how much of that would therefore fall under raid buffs.

if you have two tanks with the same dps(t) curves

Why do you keep shifting this to a hypothetical that is far from reality? Even GNB and DRK have rather distant dps(t) curves.

So no, improving a job's alignment with buffs doesn't have to come at the expense of rDPS parity.

If two jobs have different dps(t) curves that cause them to benefit differently from raid buffs, they cannot simultaneously have parity in settings with raid buffs (as noted by average aDPS) and in settings without raid buffs (as noted by rDPS).

Which brings us back to the point long since already established: If you want PLD to have parity in its actual, total contribution in 8-mans (as noted by aDPS) without having changed its damage profile, then it needs to have excessive rDPS.

Personally, I think that'd have been fine, as we don't have any meaningful 4-man content anyways, but perhaps they're future-proofing for later variations of Criterion Dungeons or the like.

There will always be some differences in jobs' ratios between their rDPS and aDPS so long as each job has a different profile/dynamics/curve to its damage, but you can shrink the most egregious examples to future-proof for balance across multiple settings (e.g., both light and full parties).
