Isn't this class trinity a bit dated now?

[Legion88]

After reading this all, there is just an official trinity, in the practice we have allready support classes/jobs.
AST is primary a supporter, 'kay it's a bit to random but it's the right step.
SCH is a supporter to, you can see it as a DPS with healing support or a healer with direkt DPS support.
And by the way, all healers are just supporters, they support the tanks to mitigate damage.
For BRD and MCH it's a different story, cause there support is mostly just for emergancy regeneration like "Oh shit helaer dead! > Manasong" or "fight takes to long all out of TP by time > TPsong". So every support of BRD/MCH will be a DPS loss, if it's not waved in dps stops at all. Every other "supporter" i mentioned has only "support abilitys" which increase the damage of the party.
So be careful with the wish for an support role on its own, you could swap more jobs to it as you would like and they and all other could reworked for this as you don't like them.

I like game mechanic based discussions, so im looking forward to see some of you on an other game mechanics discussion thread.
