I think something that's very important to note is that it's not just the trinity system that allows them to do the very careful tuning they've been doing for coils and onwards and present the very carefully designed challenges they have been. It's also because having purely static classes (or very close to purely static) gives them fewer variables to be attributing for in balance. XIV's class balance is actually very solid, and adjustments throughout the game's lifespan have generally been very minor so far, precisely because they aren't having to balance "haste ninjas vs shuriken ninjas vs katana ninjas vs tank ninjas" etc.

Two things:
1. Like it or not, players do get practice with their skills out in the open world; having it suddenly swap your moves in party content is somewhat jarring and confusing for a lot (see adjusting to PvP actions)
2. You can already do that kind of. You can just run around in your Class in the overworld and have a lot more customizability, you know. (Hell, I'm regularly in Trial Roulette as a Marauder...)
