This is really revamped from the way it worked in the first game, so here's a few related inquiries about how this thing actually works.
Is the Crystarium infinite? Once I learn all the abilities, can I just keep increasing my stats forever?
If it's not infinite, is it possible to max out all 6 roles? Possible to get all the Crystarium level bonuses?
Are the max stats achievable fixed, or do I very carefully need to balance which sized nodes I give to which job in order to not screw up my stats for endgame?
Basically, "Do I need to very carefully plan my level ups in advance, or can I just spend my CP immediately without thinking about it?" I don't want to accidentally cripple my stats.
