Any good WindBreaker builds?

Ok, since everyones saying what they did so far/are doing, I do it too.

1st job: Max all but Storm which is left at 3.
2nd job:

 Spoiler

30: 1 Storm Break(1)
31: 1 Wind Walk(1), 2 Mastery(2)
32: 3 Mastery(5)
33: 3 Booster(3)
34: 2 Booster(5), 1 Soul Arrow(1)
35: 1 Booster(6), 1 Soul Arrow(2), 1 Storm Break(2)
36: 2 Mastery(7), 1 Storm Break(3)
37: 2 Mastery(9), 1 Storm Break(4)
38: 2 Storm Break(6)(hits 4), 1 Mastery(10)
39: 3 Mastery(13)
40: 3 Mastery(16)
41: 3 Mastery(19)
42~45: 3 Storm Break(9, 12, 15, 18)
46: 2 Storm Break(20, Max), 1 Mastery(20, Max)
47: 3 Wind Walk(4)I'm here right now
[COLOR="DimGray"]48: 3 Wind Walk(7)
49: 3 Wind Walk(10, Max)
50~55: 3 Thrust (~18)
56: 2 Thrust(20, Max), 1 Final Attack(1)[/COLOR]

After this just max Booster, Soul Arrow, and dump all the other points in Storm/FA. I might leave Soul Arrow at 7 and put the rest of the points into FA though.

6 Storm Break does a lot without needing much SP, it brought my non-critical hit % per attack from 195% to 360% (if I hit the maximum amount of monsters, which I nearly always did since I was CPQing). A higher level of Storm Break also isn't really needed early on, so you're better of maxing Mastery first.

theoretically nothing is "needed" early on. A move that has 100% kb, does dmg to 6 monsters at once, and allows you to lvl insanely fast is pretty nice to max early on. Do your build how you want, but once you get storm break double shot is almost an afterthought.
