I think it is quite awesome, but Inferno is just complete bullshit. I had no issues getting through inferno act 1, dying a couple times. I'm even able to have magic find gear on, and grind my way through inferno act 1 now that I have gotten better (although some people still piss me right off).
Act 2 inferno is an entirely different story. I have used magic find gear for 4 or 5 playthroughs of act 1 inferno already (I know, that isn't a ton, but it still is enough), and nothing I find matches the gear I currently have (which was all bought for 10k gold or less on the auction house or given to me by my buddies). The fact that the game even drops a level 52 rare item on occasion is just plain stupid. It would be better off just dropping nothing.
And my problem isn't with normal units. They can generally be avoided or kited until you kill them. It is the b.s. affixes that special units get. How in the hell is it fair for a unit to have Fast, Vortex, Waller, & (Fill in Massive DPS Move). You can't run from them, and they proceed to vortex you into their series of walls you can't get out, and you die instantly. Nothing about that is skill, it is just dumb.
On that note, I will give the game 8/10. The server issues anger me on occasion, and Inferno needs some fixing for sure, but it is an excellent game regardless of that.
