1) There will be some sort of difficulty adjustment.
2) I find it interesting that some find the game too hard, while others too easy. No offense to you, but I have soloed the game with 4 different classes. Alice is wrecking the game without leveling up. Yes, a solo Level 1 character. And that is without cheesing the game. So, I hope in the future there are options to make the game easier and harder.
3) Check out my thread on combat for help.
