Dragoon plays at the same level as monk and blackmage. Try changing up your rotations if your dps is not reaching the numbers you want it to. Look at your gear maybe you have some useless or undervalued gear compared to your party. There should be no problem with dragoons even the jumps are fine. Though it is nice the animations are getting a speed boost it is not that difficult to weave jumps in between enemy attacks and player abilities.
Disembowel is also a great buff for Dragoons damage as much as a bards.
