I have to agree that the game currently seems to hard. i play with a group of ranger and shadowblade. The ranger has one skill that seems a bit overpowered. all the other skills (ranger & shadowblade) seem underpowered.
What i find especially frustrating is that the game forces me follow a certain path by how the enemy levels are spread out.
So far it seems, as soon as i go somewhere or do something the game designer hasn't thought of or did not mean for me to go or do, i will die. i find this very limiting.
