That's fine, but MNK also has more opportunities to lose a positional, thus over time balancing out the positional DPS loss between the classes. I'd wager a MNK loses more positional bonuses than a DRG, simply because they have more chances to do so.
Anyway whatever, I feel like we're saying the same thing and our difference of opinion is mostly semantics etc. etc. DRG is in a good position. Whatever DPS they lack is made up for by the increase in damage a BRD gets from Disembowel and should be counted as DRG DPS because it is damage the DRG makes possible, just like how Foe's Requiem DPS should be counted as BRD DPS (in my opinion). I don't think it's standard practice to "shift" DPS numbers from one class to another like that, but it seems entirely appropriate to me.
