That is because you're operating under the belief that balanced = Fair. This is not the case, and never should be the case within game design.
Utility does tax your personal damage because the utility you provide through your aDPS is significant in the context of the raid.
Does SAM/BLM provide it? No. Therefore they need to provide more damage. If the other jobs were to be competitive with them damage wise, that would not be balanced.
As it stands, BLM at the very peak seemingly outperforms SMN by 8%, and RDM by 6%.
That is fine.
If anything, SAM should get a buff since its currently competitive with RPR, which may provide a "crappy" raidwide damage buff and a "crappy" shield heal, but those are things it provides which provide flexibility to the class.
Otherwise, again, for what reason would I bring either of those two jobs when the one right below it is performing within 2 or 3% on personal damage, AND provides utility that neither of those jobs provide with less difficulty in obtaining said damage?
Not all classes need to be within the perfect 2% to 5% margin of the other.
If we provide EVERY class with some form of raid utility, then we just move further and further to class homogenization. The game really doesn't need that simply because people get obsessed with the numbers not being similar enough.
Or maybe SAM is undertuned if BLM is that much better of a choice than it.You'd bring a Samurai only if you'd have a Dancer in the party. Here's the difference however.
All melee are having competitive performances. However, for casters, in term of performances, Black Mage is simply dusting both SMN/RDM. You ideally only want to bring 1 selfish DPS. That means your ideal comp is something along the line of RPR/MNK/(BRD/DNC)/BLM. You'd partner the BLM on DNC. There isn't really a spot for SAM unless you do something like MNK/SAM/(RDM/SMN)/(DNC/BRD). I'm telling you, in term of raw performances, BLM > all casters in term of DPS. Black Mage is either too powerful or SMN/RDM are undertuned. Whichever SE decides to pick.
I could see SMN getting a buff but I can't see RDM getting a buff.
I've no idea how to properly multi-quote.
Ah, wait, there it is, I think.
