A well geared RDM can give you a DD with the power to heal & access to magic damage if needed while providing some buffs to your other members, keeping your mages MP up if they do not have MP temps, and debuffs on mobs. Given, this is not often very helpful right now, but sometimes you can make it work, DDing can be done if you have good enough gear in VW, as I said in the other thread, I was 2nd & 3rd 6 fights in a row against Aello excluding 1 with a bad start.
