This also comes down to class and fight design. Casters have movement tools. Even BLM has enough to handle a few unexpected mechanics. If FF shuffled mechanics to be truly random in existing content that would strain casters, but we could also step away from complex puzzle like mechanics or space them out.

I completely agree with you that the simple route of making everything a dice roll has problems, but we don't limit ourselves to only doing that I think it opens up a lot more possibilities. Class abilities should probably be tweaked in response too and move away from totally rigid rotations. They wouldn't have to be completely free form but they would need some amount of flexibility built in. I'm in favor of that even if content stays the same.

This isn't to say they couldn't do it, but if they put restrictions on how often a mechanic can go off due to said factors, it can lead to fights that get more scripted as you go along as there are less places they can go. Of course, you could just ignore that and say casters just have to deal with it, but then you either potentially don't bring casters (except SMN) or you are just waiting for the run where the RNG lines up.
Major mechanics absolutely would need some kind of restriction. In a purely random setting you could encounter something like an infinite loop of M2 hearts. Pure randomization might be better used on smaller and less complex mechanics like stacks, raidwides, TB's while major mechanics are space out and perhaps just swapped in order.

If SE were to seriously consider revamping fights it would probably be best to limit it to a dedicated zone at first like Eureka or Bozja. That would let the devs and players experiment while also avoiding the need to revamp old content or disrupt current content grinding.
