Would people be against the dev team coming out and saying "Enough with the holy trinity, we don't need to copy WoW 100% this is a Final Fantasy game"
And then they added to it so we have Tanks, Healers, DPS and support classes! I always thought the game would be better and maybe have a bit more depth if hypothetically party set up was like this
1/1/1/1

1 Tank = Paladin
1 Healer = White Mage
1 DPS = Dragoon
1 Support = Time Mage

or would be now be hearing stuff like "Time Mages shouldn't DPS!" ???
The game would have to undergo lots of coding and balancing so it will never happen most likely but I always assumed the 4 party dungeons were a little nod to how party set up was in the older games where you would have a healer and a support class with you.
