This is probably because FFXIV cannot truly have job identity, the proof of that is what happened with Pictomancer.

It launched overtuned in terms of DPS, and the effects were immediately noticeable: DPS checks in Savage were getting trivialized. SE eventually responded with a potency nerf to bring it in line, and things settled to the "It still needs a nerf but ok for now" category.

Then FRU arrived, and it revealed just how powerful a "downtime-optimized" job could be in Ultimate content. Player outrage flared up once more.

So another adjustment comes in, this time the nerf stripping away the aspects that let it overperform in downtime-heavy content. Once again, the balance complaints stopped… and the usual "grr, homogenization" talk returned.

Unless every encounter is tightly controlled to suit every job equally, which is impossible, true identity will always create imbalance somewhere in current fight design.

The only real thing they can do is make jobs homogenized pre-8.0 (for older content), then have identity post-Dawntrail, where encounters are designed around each job's uniqueness.

It's a poor implementation to have your job play one way pre-8.0 and another way post 8.0 but what else can they truly do ?
