It seems Ninjas have it best in keeping dps numbers from Dummy to Boss Fights, Monks have it worse and Dragon's new skills make them have it the complete worst.

At least thats what I'm hearing from other dragoons. Getting Monk Positional and keeping optimal dps as monk is the same as it's ever been, nothing big has change for the class from heavensward except we got a lot more oGCDs to use in fights (Shoulder Tackle, Elixer Drive, Forbidden Chakra, Tornado Kick).
