We're going to make the game a bit more tolerable for melee DPS

[Atreides]

No you don't get more dps out of a melee class. Summoners are still up there, followed by these crazy black mages and sometimes these shiny bards. Can put a monk between black mages and bards but you ll never outdps competent and adequatly geared ranged.

Either I missunderstood you, if thats the case I am sorry but it takes a really incompetent melee if he gets outdpsed by ranged in those or any fights this content has to offer so far if gear is not the issue.
I don't know much about Dragoons at last for Monk I'd have to play really terrible to not come out on top though.
