What's wrong with Diablo 3?

I consider myself to a veteran of sought's in the Diablo realm having played Diablo 2 and the Lord Of Destruction pretty much every day for years in my teens and then returning to it a couple of years ago still enjoying the gameplay but obviously by then it was pretty quiet online so that stint didn't last as long, about six months or so. Also played the original a couple of times which i also enjoyed, now given all that i was obviously looking forward to Diablo 3 and with a long wait over ten years came allot of anticipation. Unfortunately i wasn't able to play from launch as i needed a new laptop, but now that i've spent two weeks with it i have mixed feelings about the game with the lingering question many are asking and debating, what's wrong with Diablo 3?

You may be aware upon reading this that although it was the biggest launch of any PC title to date player numbers have been falling every week, some put down to the lack of server space upon launch which i didn't experience but i would give Blizzard a pass on that since they didn't anticipate such huge sales. But at the same time it's a mess they created by making purely online play, few played single player much in D2 and i understand they want to combat piracy but at least it was an option for us when lag was just too much online which is a BIG problem for D3. So some say this put a foul taste in the mouths of players who gave up on it early on but also predicting that many of these players will likely come back as things improve, i'm not so sure i think it's a number of issues that have driven people away. My thought's on the problems:

For the life of me i cannot understand why Blizzard tampered with an established RPG model by removing the ability to customise a characters atributes making each character unique. This is perhaps the important part of an RPG, building a character from the ground up making sacrifices early on and sometimes struggling so you can save up stats for the right skills and attributes later on, this is something i enjoyed but no longer as Blizzard have gone for dulled down form of character building. What they have done is needlessly removed the ability to make a character unique, this doesn't just dull down the gameplay but also limits the replay-ability of the game, instead anyone can make the same character as you. All they need to do is arrange the skills & runes to match yours and buy the same items, what's unique about that?! It's such a glaring issue with the game i'm amazed Blizzard chose to entertain going down such a route let alone implementing it, i have to ask...why?!

The next glaring issue is lack of content, for a very long awaited sequel it feels very short especially for the last act the adding of inferno does little to make up for it especially as it's more frustrating to play in such difficulty that any else especially for a Barbarian class or Monk. I'm also not sold on the graphics, this was the first problem many had with the game in part because it wasn't dark enough which is still the case depending on which area you're in however i do think they addressed this issue for the most part. The ral problem for me is that the graphics are indicative of Blizzards approach to gaming today, accessibility, it's not about pushing the boundaries to make a game that looks stunning it's about making it so more people can play it thus higher sales, they go for the money. No, this is PC/MAC gaming, it pushes the limits of what can be done if you don't have a system that can support it tough, either improve your system or get a console, don't advocate holding games back so you can play them.

The next issue is the auction house, now they claim that this is to make things easier for us, maybe, but i don't think that has ever been the main motivator, it's to make them money sacrificing gameplay yet again and production time on the game itself likely playing a big part in the lack of content. In D2 i and many others enjoyed the trading aspect which is now sidelined, i enjoyed haggling with people and getting a great deal for things i needed sometimes trading for things i personally didn't need but knew i could use them to attain the item i wanted. This also leant to the re-playability factor as you would play through the game to find items for trade, this still happens of course but when you can just get gold and buy it from the auction house, why bother? Or even spend real money on it as i'm sure many do? All i've been doing the past week is playing to get gold, for the auction house, this is no way to enjoy a game, it's a way to drive you away from one.

A rather long explanation of what i think is wrong with the game and what is beginning to push me away from a series i love, i've maxed out my barbarian and only need a new weapon for him and he's done after that i think i only have one or two characters left in me with this game. So i want to know, if you're a Diablo veteran like myself or if Diablo 3 was the first in series you've played, what do you think is wrong with this game? Is it one issue or a combination like i consider it to be? And will change come?
