I have to point out that "balance" is 50% actual objective balance (which, for example, RUN is supposed to be balanced against PLD such that they are equivalent... But they aren't.) and subjective balance (job A only plz).
The subjective balance is based on human nature... And as we all know, humans are just pigs in clothing.
So it will take time for humans to stop being stupid about things like pt setup... (Ala when RUN actually IS comparable and interchangeable with PLD... Do you honestly think it'll be less than a year before the masses accept it in PLD's stead?)
And to be quite honest... There is and always has been only ONE content in this entire game that actually had 100% job balance: VW
That's it.
Every other thing to do always favored some job over another and this made the subjective balance flare up.
But VW?
You always benefited from having at least 1 of anything... When shouts ask for SMN in endgame content with equal frequency as PLD or WHM or BRD... THAT is a balanced content.
But this by no means makes VW necessarily GOOD content. (I realize that 99.99999% of humanity can't distinguish between "you are stupid" and "what you just said is stupid/your idea is stupid"...)
VW was an artificially prolonged content.
Unlike, say, dynamis wherein you're only real deciding factor is real luck. (Getting relic A vs B which you wanted)
VW extends it's life via having abysmal drops.
Sure, it's possible to have ALL dynamis items... But it can take years to get them. And then there's always the upgrades to them... Which requires more dynamis.
The ONLY thing that extended VW's life was the fact that drops were so bad and were good.
Had VW had the droprate of Delve... VW would have been completed as quickly and as easily as Delve is. (Most ppl I know have either everything from Delve or everything they want from it.)
