I put this game down when it first came out as I hoped for DH6 and it's not. However, I decided to check it out again as I'm plateauing in DH5. However, I've noticed half way into board 2 and the enemies I'm going up against are outlevelled from my team. My highest character is 16 but majority are in the 9-10 range.
How is the best way to bring my straggling characters up in power? How is it I can acquire both gear as well as characters/material to grind into what I want to keep to train them? The progression feels a lot more complicated than DH5 due to its team focus.
