Dual Blade and SP saving / Job Advance

The way it is currently is that you can save 1st -> 2nd -> 2nd+ and 3rd -> 3rd+, they changed it like almost a week into the official kMS release and had to give out free SP resets to those affected.

But that still doesn't remove the problem that if someone who manages to get to lvl 120 without using the Cash-Shop Mastery-Books, still has 25 SP's at lvl120 that he can't spend -anywhere- on lvl10~120 skills, and if Hazzy is correct, and maple uses the normal job advancing procedures, you can't make the 4th job advance if you still have unspend SP's in your skillbooks.

If you can't spend the SP's before 4th job, I would say, its bye bye 4th job for ppl who don't pay NX... Unless Nexon did something new here... :o
