Whoops Square-Enix! Class and Job reveal for ARR.

I've heard it suggested that Musketeer would be like the ranged Monk. High damage against a single target kind of thing.

I'd be ok with that.

Should be fine as long as it also has some AoE that makes sense for a musket. Something like a scattershot that fans out in a cone in front of the musketeer, or explosive shells that do damage to a mob and any other mobs within 5 yalms of it. Roster > Niche, and yes that also applies to DPS.
