Second job
At level 70 your skills should be similar to the following:
 * Bow Mastery (MAX)
 * Bow Booster (MAX)
 * Final Attack (0)
 * Soul Arrow (MAX)
 * Storm breadth (MAX)
 * Wind walk (MAX)
 * Thrust (MAX)

Why not add Final attack? You already have Bow Booster Max and can fire arrow very fast. There is a no need to add final attack as the success rate for it is not 100%. Sometimes it will not fire another shot. Bow booster will succeed every time you fire an arrow. It will always remain fast until the skill time is up. Save up the SP and add it to another important skill.
