I have 3 3-man teams I play with friends; 3x DH, 3x WD and 1BB+2Monks. The ranged classes are by far the easiest, with the WD's being the easiest to keep alive in sustained AoE fights. My melee team is only up to about 20 but it's far and away the most frustrating team dealing with knockbacks/fears. It's like playing WoW without follow and with a fixed camera angle. No assist means individual looting all...the...time. Spoken plainly, you'd be nuts to pay a monthly sub to box Diablo.

That said, it's not terribly difficult to make money, it's easy to get started, you don't need to overgear content until very late in the game and buying superb gear for leveling is fairly cheap on the AH.

I haven't tried the RMAH; I'm just not ready to open myself up to that sort of risk.

D3 is MUCH more hardware-dependent than WoW. 3 clients at super-low settings with the 2nd two set to maxfps of 30 still bogs badly in any area with lots of smoke or water. WoW was liquid smooth even with 5 clients at medium and one at max. My PC would also 5 box Rift at good settings, so this is entirely an engine issue.

Yes, you can group with friends. It makes it a bit of a waste of time for them if they're higher (they one-shot everything and get shit for XP) but you still level fast. It's basically what everyone wishes PLing was like in WoW for us boxers.

Loot...meh. I'm doing it because it's harder to manage than WoW (challenge) but it's grinding me down, to be honest. Just so many little things that distract from actually playing the game; mostly pathing...wierdness/oddities for lack of a better description. And of course, having to login to play and lagging like hell on Sunday is always such a treat.

My 1.5 cents, anyway...
