Blade and Soul actually have no Trinity System. As far as I know every class is a DPS-Class. Finding people for a group is much faster, because you dont need to a specific class to fill the group. There are also exceptions here, but combat is just like: "Beat the crap out of it, but beware of mechanics". I think that most classes got their own selfheals and potions.

It would be too drastic to remove the holy trinity system from FFXIV. Its ok to have fixed roles for each class, but sometimes I wished to have much more variety in each class (skill trees or something). On the other hand, its annoying to have people like "Do DMG as WHM" or "Supporter-Class sucks". At the moment, 90% of its content is still based on Damage rather than playing the actual job.
