I think Raise tax on RDM and SMN should be completely removed along with their Raise abilities. Instead, SE should implement Raise in an item form like Phoenix Down. Give it a good recast like 10 mins and a cast time of 8s like regular Raise. That would allow the jobs to be balanced solely around their dps and raid buffs while also allowing DPS classes to raise in a pinch when healers can't afford the time or mp to do it.

Nobody wants their dps to be hamstrung by utility they won't even use during clean runs.
