I'm current 5/5 on Melee and Ranged atm, but I plan to move those Melee merits into Magic when I get the chance (1mil exp into a new merit ws, first). I'm also 1/1/3/5 on group two, and I can honestly say I love-love-love Role Reversal, and almost never use Ventriloquy. Even with repair kits, I have more HP than my mage puppets, so when there's a WHM available, or I'm subbing DNC or SCH, I will gladly give my HP to the puppet for a quick Reactivation without having to waste an Oil or wait on Regen. When I'm helping friends farm currency in Dynamis and I'm on PUP/DNC, I'm probably using Spiritreaver. After I WS and take a few unlucky blows, Role Reversal will save my life with a much greater frequency than letting 1 mob kill my automaton (while possibly more continue to beat me up). That being said, in tandem they can work wonders with Oil's strong Regen.
