Difficulty (Divinity: Original Sin)

A lone wolf started playing for a fein warrior with a perk, took the red prince to the party, went to play and ... and sucked himself. I don’t understand what’s the matter, the complexity of the classic, I try to complete all the tasks, but either overleveled all the enemies, or it’s impossible to kill anyone together, they will smack you in the face whatever you do. Question: how to play then? I am in despair, I went into the swamps with the idea of ​​shaking the levels, because in Fort Joy all the masters attack and rape me without a chance.
