They lose half of Alchemist (the increase in buff durations, aka the useful half - percentage based potions are still better than 170% improved non-percentage potions), Shadow Meso, Meso Up, and Avenger in 3rd.

Haha really though, 6 new 4th job skills, I don't want to buy the equivalent of TT30 again. Six times. Just to get the same mastery skill and w.atk bonus skill that every other 4th job class has now. Plus a 30 second cooldown Ult, and a couple buffs to 3rd job skills.

Aerial Barrage, 3rd job skill that links from Rush is worth using if you can OHKO with the combo (Rush + Barrage), or if the monster has high HP and can be instant-killed, i.e. PQ monsters.

I used Leap Tornado as I went side to side in a flat map to train since it was more entertaining than purely using Strike Dualshot, but Strike Dualshot is more useful in most situations. Good maps for Leap Tornado are the Pirate Map, and there are some abusable slopes that you can spam it while standing in Leafre. I think it's one of the few things that really depend on good timing, since you can cover good distance while attacking with Leap Tornado. If you're really good at it, it's possible to literally match Acrobatic Jump's horizontal movement speed when using Leap Tornado with it.
