I'll keep it short.

Pros:
1) Great mechanics that while I feel need to be tweaked to be balanced across the board, are good fun!
2) Interesting story.
3) Graphics are good.
4) New races!
5) New skills!

Cons:
1) Magic >>>> Physical classes. It's out of control!
2) This is because CC is out of control in this game and it ruined my experience from a co-op perspective having to play around magic users in my party and never the other way around.
3) Elves seem a bit too strong compared to the other races.
4) No dialogue (I know it's getting fixed)
5) IMO, when a player in coop talks to someone, you should be stopped in your tracks to see the dialogue in place regardless of where you are so you can see both how they react and choose through the conversation but also know you just picked up a quest. Further, when another quest person is discussed, it should alternate people in the party who gets to talk when you have someone who is just charging on ahead clicking on everyone before you.
6) Give us a better loot distribution option.
7) Better item organization.
