I'd actually support this.

Supply a turn in system for tokens that you aren't going to use, or make them drop from specified roulettes. Then make a fight cost 10 tokens and make them drop something decent or glamour-y. Maybe a "BCNM" token that allows you to turn in for a dungeon armor drop of your choice or something. Something useful for gearing new jobs, but not game breaking. Make it casual and fun content.
