Not always. It was fairly easy to change your trees around in EQ2 and you could even save different builds I think, but that game suffered from having really good and desirable skills in x tree and then total crap in the others. It's a single player (or co-op) game, but Borderlands II would be another good example. It's fairly easy IIRC to swap your skills around to try out different builds and they all have the traits of the base class but play just differently enough to keep things interesting. Unfortunately, it would require a lot of dev resources to balance everything properly and I don't think FF has the dev team they would need for it right now.
