I think it would just be easier to replace Verraise with like Vermedica or something, and buff RDM's damage. I have Thoughts™ on why Verraise is actually hurting RDM's identity that because of it, RDM is basically forced to play permanently 'white shifted' when RDM is all about balance.

And then rework Summon Phoenix, make it like a 3 minute cool down separate from SMN's damage rotation, and lock a couple of instant rez charges behind the summon while also buffing it's regen capabilities. Should water down SMN rezzes enough to also warrant some damage buffs, and gives SMN a pretty cool, and thematic situational summon.

And finally reduce the cast time on healer rezzes down to 3 seconds. If we're removing rez responsibilities from DPS, then it needs to be made easier on healers.
