"meh"
Combat feels slow, and you really don't feel like a hero. One problem is that mobs scale with the player so you never get that feeling of being powerful. Mob scaling is just really bad idea game design, it just makes the game feel really bland.
Game control really could use some work. Plus there are line of sight issues where you can't see some doors and at time lose complete view of your character.
Itemization isn't very exciting. Good items are extremely rare and hard to get. Which would be more bearable if there was the ability to buy and sell via a permanent player auction.
There is no ability in multiplayer to start your own game.
One nice feature is the shared stash, which is a game feature that should be standard in all these types of games.
Overall the game lacks rewards and combat just isn't fun.
This game is no Diablo.
