It's okay to use Wounded Cerberus for the early game, he's the best demon you'll get for awhile. Since you are a melee fighter, don't put more than 10 points into VIT or LUC, put the rest of your points into STR. Also, you should probably raise spin, although I don't know much about melee builds, but it seems like spin is pretty useful. I don't think rush is too useful, but you might need 1 or 2 classes in it for something, I'm not sure. Also you should raise weapon knowledge too, and talk is useful upto class 1 rank 5 as well.
Actually I'm probably gonna go to bed soon, if you're on tommorow maybe we can play then.
