Exactly Kazimir, I just posted this in another thread about FFXI Job/Sub Job system and how there was nothing wrong with it and I think it ties in well here.

The thing is people think FFXIV is great because you aren't "pigeon holed" into a role, but that is because the game is still young, FFXI was the same when it came out people used lots of different sub jobs. Once the game matures people will expect you to have certain abilities and if you don't you will be gimp, there is no avoiding that it will happen. Only thing is, that in FFXIV it will be 10x worse for you because instead of having to level that one job half way to have the sub job of choice you will have to level lots of classes to cap maybe just to get those select few abilities that everyone will expect you to have.

For example as soon as something like Utsusemi comes along it won't matter what class you are you will be expected to have it on your class, so will have to level whatever class has it to that level just to get it.
