I think Reaper will play like of mix of DRG, SAM, and DNC. You will have your regular combos that build a gauge that you spend on oGCD attacks similar to SAM. Those attacks will fill another gauge or a charge system that when full lets your transform like DRG does. This will change your basic combo attacks like DNC does. I don't want it to have positonals but it probably will. Might have a DoT on one of your combo enders or something. A self buff you have to keep up that might be on a combo ender. I think unless they give it a debuff similar to NIN's Trick Attack it'll be pure dps like SAM. But all this is speculation.
