I think I'm grinding this game a bit. I'm at 30 hours and just finished chapter 9. When I completed it and looked at my crystals, I had 55,000 points to use. :doh:

[spoiler=for those who finished ch 9]I've unlocked the ability to use any of the skills for my characters. Did you guys even bother making them learn anything new? Is it a waste of points?[/spoiler]
