Skill and Stat progression is -very- important to me and many others I imagine.
You can tell how I show my love for this here.

And correct me if I'm wrong because I admit I am rather ignorant on the subject so I apologize in advance if I am in the wrong but. From what I've heard, Diablo 3 was a testing the waters experiment for cash shops in games. Even though they've been done before, this was blizzards attempt at it.
As well I've heard the "loot" system isn't up to par. Statements that stay in my mind are the ones like "the loot doesn't trigger a dopamine effect", which I imagine was more common-place in previous entries to the series. Could these loot junkies have a point?
Another thing to consider was, weren't they working on a pvp system for 3 years and then scrapped it when they felt it wouldn't work and then shoehorned in something real quickly in less than a year? If so, I'm sure that went down well.
Almost forgot the always online thing. I do not need to explain why that is bad. This shouldn't even be on here, it should have never existed as an option to begin with.
Also, I don't need to add that offensive quote from a social networking site, everyone knows what was said, pretty sure everyone's tired of it. And I know I'm tired of being let down by companies I used to trust. :[
