Chapter 11 is awesome.

The game opens up a lot and the difficulty spikes up for a nice challenge.

So far I've only had to do about a 30 min grind session cause a boss was giving me trouble.

Oh and if anyone needs a grind spot in Chapter 11, let me know. There is a group of mobs you can kill in less then a minute that gives u 8k CP. You can run a bit away and come back and they'll respawn.
