I don't want to play with 4 people, I don't want to do the undead first, I want to take out the enemies I want. I want to solo the game with 2 stealth archers, not with their stupid rulesets that will not allow me any freedom.
Seriously. You are making things very hard for yourself. Unbalanced party and with only 2 people. No wonder it is hard.
It is like playing Call of Duty and complaining that you can't win without shooting.
The game is designed to be played with a full 4 player party with a balanced set of skill.
