Oh, they could most certainly remove them. It's just a matter of time and money, which they want to spend on other things.

That's why I said both the coding and lore. They most certainly could remove them, but at this point, the time and effort is better spent on newer things.

For SMN/SCH I was thinking of broader concepts. ShB did separate these jobs a bit further but there are still Aetherflow mechanics in SMN for instance, although they are not tied to anything anymore. We could just have Fester / Painflare on the same CD and work just fine. They still share the same EXP bar too. SCH's Ruin II feels odd to me when you don't have other Ruin spells.
While they could make one job the continuation of ACN, and the other one a stand alone job...
Anyway, that's not a priority we can agree on that

You aren't wrong in that regard, but at that point it's about altering how each job functions, not separating them. But, they can't fully change certain aspects, since SMN and SCH are meant to act as parallels to one another. So Summon, Artherflow, Aetherpact, certain elements need to appear similar to maintain that connection. That being said there are some things that don't make sense that I hope do get rectified come 6.0.
