maybe jumps and tp gain? i dont know.
Serious response to silly idea: (No offense but it really is.)
Jumps give the TP of another weapon attack, and I am not 100% sure, but it probably does not account for the off hand when dual wielding. While jumps are good for DRG where this means 20+ TP, for NIN, this will probably net around 5 TP. Additionally, ja lag will delay your next attack. Overall, jumps will actually reduce your TP gain as a ninja.
/WAR probably wins for the already mentioned DA/Attack Bonus/Beserk/other goodies
