I feel like MCH, NIN and sometimes DNC based on fan procs(unreliable) is the fastest we are going to get when it comes to APM. Something tells me that Reaper isn't going to be a high APM job. At least based on what we've seen.

Only thing we really know is that thus far Reaper is DPS Warrior with the knowledge that they have 1 combo, an oGCD and a Berserk/Delirium/Requiescat burst mode.

I think Reaper is primarily going to serve as a foil to Dragoons as far as the "buffs" go.

Dragoon will focus on sustaining Blood of the Dragon during encounters while Reaper is more going to have it's buffed state be active and needs to do as much damage as possible if it cannot be refreshed.

Like all new jobs I have a feeling that Reaper and Sage will start out strong out of the gate before being knocked down a peg.
