Couple suggestions

Make Refresh castable on self-only and probably change the name(Regain maybe?). Every other caster is able to activate their own MP recovery skill(Blizzards, Luminiferous Aether, Aetherflow/Energy Drain, Shroud of Saints), then there's BRD/MCH with their MP recovery abilities, so RDM doesn't need someone to be demanding their MP recovery skill.

Double/Triple: costs 175-200%/250-300% to do 2x/3x damage

More fencing-styled names for the sword skills.
