Don't waste an SP change for a Cygnus Knight.
First and Second Jobs don't make a difference as you have enough to max everything in 2nd.
First Job: Max everything and leave Storm last.
Second Job: Storm Strike is your main mob move, so go get that early on (At least 1 point). After that, go for at least 1 point in Double Jump. Any additional mobility is good. After that, aim for Mastery to 5, Booster to 6, and then Soul Arrow to at least level 4. After that put 1 into Strafe for a 1v1 move. After that Max out Mastery, then Double Jump, then Final Attack, then Soul Arrow, then Booster, then Storm Spike, then Wind Walk last. As you have remaining SP before 70, put them into Storm (1st job).
Third Job: Get Arrow Rain to level 4 at least. Then max Eagle Eye. Then save 50 Skill Points! After that, max Arrow Rain, then max Wind Piercing, then Evasion Boost, then Puppet.
Along the way you will get Concentrate (At level 100), and then Hurricane (At level 110). As soon as you get them, max them out with the saved SP you accumulated (50). Finally, level up Wind Shot.
