I would like to know more about this as well. I'm finding it difficult to make a party in the way i like to play. I prefer a rogue/mage hybrid lead character (always have) that does the looting and talking. Creating this character seems impossible because it stretches attribute points very thin. Without knowing what a maxed attribute is or attribute requirements for highest level gear it's impossible for me to make a party I'm comfortable with.
I've reached L5 with 4 different parties now. Beating my head against a wall here.
