Class direction for 'support-oriented' classes (BRD, MCH, AST)?

[Ashkendor]

Understandable, but I could see 1 support role in each party which could essentially empower the 3 other dps in the group to increase their damage significantly, or apply vulnerabilities to the boss, etc. A support job could even synergize with other jobs with their skills, such as having the ability to empower ninjutsu of ninjas, empower the jumps of dragoons, etc. I know it would require some balancing and job tweaks, but I personally would find it more interesting.

The problem with full support jobs is they almost always end up being either required or useless. It's really difficult to hit that middle ground where it's useful enough to take with you (i.e. it makes up for the loss of the 4th DPS) but not overpowered.

They've flat-out said in one of the Live Letters that there are no plans to include Support classes for this reason.

Right now we've got the MP/TP regen, and a couple of weak debuffs, but that's it. The regen in particular is rather useless if you have a competent group outside of doing chain-pulls or Savage, because practically every class has some skill they can use to regen their primary resource on their own.

If doing casual content in a casual manner (i.e. not speed pulling) is the bar to measure skill usefulness by, 90% of my kit is useless.
