As everyone else said it's not as good as Diablo 2, but it's still the best game of the genre we've had since Diablo 2 imo.
The game has massive imbalances (my warrior soloed the snake boss after the temple of Xeria. Soloed. All 3 heads. And only drunk one potion while doing it), it's pretty bug-ridden, the difficulty is not well gauged imo since I often play like shit and barely do more than chain right click on the bosses with my war while my priest is on auto heal, my necro on auto death heads and my ranger on auto shoot and I still win 90% of fights without even having to drink a potion as long as I AE taunt, but all in all I'm having fun with it and some fights are neat like the tree boss.
It's good for a couple dozen hours of mindless fun
Oh, cute bug. On warrior type characters if you get taunt, you can use your long recharge abilities, switch to taunt during the cooldown time and since the game doesn't remember which ability you last used, your cooldown will be the short 15 seconds taunt cooldown allowing you to basicaly spam long recharge AE shit.
