Is ranged support dps needed as a job type anymore?

[Reinha]

Try having to stand still and do mechanics when the fights are HARD. Sure you have them memorized now and are over geared.

Which dps jobs have to stand still? BLM. That doesn't explain why other ones blow ranged jobs completely out of the water. RDM and SMN can raise and heal but they do more damage than MCH and BRD who can't. Some melee have healing utility and they do so much more damage that bringing a ranged is not even worth it for the 1% party bonus.
