I 100% think that RDM is going to get some sort of ability with the name Refresh as a ref to XI, whether or not it operates the same. As for damage abilities, RDM is designed so perfectly that adding anything to its single target feels like it'll disrupt the almost choreographed flow of the job. Maybe a third finisher ability that's aligned with neither black/white magic for when you finish your melee combo with a balanced amount of mana that could proc Impact or something
