To add my voice to the fray, adding more roles screws with party dynamics. Queues would take a lot longer because, unsurprisingly, support ends up being a role less popular than tanks or heals. Games with a support role has groups being held hostage by them. Conversely, they aren't worth a damn if not powerful enough. Hence why it is known that support tends to be either overpowered to the point of being mandatory, or underpowered and an effective waste of game assets. That's not even going into classes/jobs that get shafted as a result of the existence of support. *points to signature*

Except it doesn't, and implementation of BRD and MCH has backed them into a corner because they're trying to insert a paradigm inside another design paradigm (DPS). It was cute at 50 when BRD was the only job built around that, and I figured they would take steps to make it fall in line with the other DPS instead of further segregating it.We have "Support" BRD and MCH falling in some grey zone that justifies their lack of DPS output
WAR isn't a good example of anything other than a bunch of undealt oversights that need to be addressed in a way that a) maintains the tanks balanced with each other and b) doesn't compromise the design of the other tanks.WAR on the other hand is on the opposite side of the argument, that it can pretty well fulfill DPS and Tank and out DPS common players on specialized classes.
We've ended up where we are with WAR because they're desperate to give tanks diversity in the wrong places, and it's blown up in their faces (considering Deliverance is there for off-tanking WARs just like Clemency is there for off-tanking PLDs; I highly doubt WAR was meant to swap back and forth and using back to back Fell Cleaves when tanking).
