Not the same thread you've seen before. It should be clear that the closest thing we have to a support class is not bard but Scholar. Make is so that the division becomes:
Tank: Mrd, Gld, war, pld
Healer: Cnj, Whm
DPS: Arc, Acn, Smn, Thm, Blm, Pgl, Mnk, Lnc, Drg
Support: Bard, Scholar

This way, groups will have the option of having the dps oriented support or the healing oriented support. Scholar's base class is still a dps class and with cleric stance it can still fulfill the regular dps duties. While we are at it, seal the deal by restoring the old effect of rain of death so that both scholar and bard have a mitigation skill.

Yes, I'm aware that this only leaves one healer job, but when the next wave of new classes and jobs come along, maybe this opens an opportunity for a melee type healer (like a medic class). It just occurs to me that scholars have the most support abilities out of most classes. It has the fairy aoe haste, fairy aoe damage reduction, fairy aoe regen, fairy aoe heal buff, several shielding skills, several mitigation skills, etc... Along with a weaker heals than the pure healing class whm. While bard has the aoe tp regen, aoe, mp regen, aoe resistance debuff, it used to have an aoe damage reducation, etc... along with weaker damage than a pure dps class. This is a perfect balance and as long as they add another healing class to prevent healer throttling, this should work out fine, where people will choose whether they want the support healer or the support dps. Of course premade groups will be completely unaffected so you have no worries for the content we currently have.
