if youre at orphan youre at the end boss ... you should just finish the game and unlock the full crystarium before you do any grinding

I'm currently 50 hours in, at orphan or whatever the wierd place is called. I'm at chapter 12 thought.

Went back to Gran pulse to quest a bit, then i was bored outta my mind so i just continued a bit.

So i'm right after the small dino and the big one.
