To be honest I wouldn't mind if healers and casters got more personal mana management cooldowns in exchange for Refresh and Mana Shift being combined into the MP equivalent of Goad and given to all of the caster DPS and ranged DPS. Remove Tactician and do the same with Goad, give it to the Ranged DPS. Same goes for the melee DPS and MCH needing more TP for AoE.

Every dps should be able to contribute to resource management in a pinch, mainly as recovery if someone dies. Ranged DPS are better because they can support TP and MP at once as is their niche, but don't completely negate the need for it at all by existing.
