So much this.
Please dont try to make FF 14 WoW 2.0. I've never been a fan of (the illusion of) choice, because that's what it is. While it may only be the optimized way - we know what players make out of it: There is a wrong way to play and a correct way. Did any of you really play WoW with a freestyle talent choice? Because in every raid environment i was ever part of, even the most casual that was kind of a no-go.
Heck we even made jokes about this: The minimum treshold should be to know how you skill - so different skill ways for me, are mostly a noob trap and don't add anything.
Now if we talk about talents 2.0 it got better, and maybe now with 3.0 there may be an acutal choice, but still another problem remains: This will widen the gap between players, and in the worst case: classes. One thing i really like about FF14 compared to WOW is job viability - you never have to tell someone: you cannot play this job it's garbage (except for BRD maybe, but this is personal bias not founded on facts). I mean its nice if you have 44 different specializations, it's just stupid if half of them will never be invited to a group because they suck.
There is a lot of customization in FF 14 though - visual customization, which personally i prefer much more. If you don't - that's fine - but please push the game i enjoy to make some weird WoW 2.0, because you got some checkboxes in your head how a mmo should be (which is thoroughly biased by playing wow for years...)
