I've read through each page of this thread and I find that a lot of the people who are complaining are:
1.) D2 veterans
3.) Late buyers, missed the boat on the early economic boom... No, the early economic confusion and fluctuation, getting away with selling crap for a ton since that's what was currently the best thing found.
4.) Players who failed to predict the major movements the AH/RMAH will inevitably make as a free trade market (which is a game in itself-- with fun wildcards like patches)
5.) Received the shaft end of the deals with the onslaught of fun slaughtering patches
I, myself, usually stay neutral in complaints such as this but sweet Jesus. I have put in 500+ I don't even know or care to make sure but I have a friend that put in nearly 900 hours played, has two tabs and two charcters full of legendaries and gets the 'phattest' of loots. Finds at least 1 - 2 legendaries/set items per day, whereas my other friend who puts in 3-4 hours a day playing the auction house. The one who "Plays" the game is loaded but finds it ridiculous to spend this life savings to close a dps gap. The one who only plays the auction house, makes just as much as he does and some more since he's made about $1,000+ in RMAH just flipping between the two auction houses. He has several accounts he has purchased with his earnings and continues to snow ball up until the collapse of the economy, which is about when the UNid exploit came around. That's when it's time to reel it back and watch the "news" and by "news" I mean the patch notes, and predict the next economic movement (He's amazing at it).
However, I do feel that Diablo 3 was a good game. The story was forgettable? Yes. The auction house was NOT tested, NOT controlled, and NOT ready? Yes. An economy with no actual money sink (item gambler, socket creation, etc) is a terrible idea, it only works when the amount of money printed is controlled. Also, gold never found it's dollar value-- long story short, it just didn't add up.
Once the things that Blizzard has promised us on the upcoming patch 1.04 goes live, I'm sure it'll balance the prices to what it's actual worth is and every object/item in free trade economy ALWAYS has a pre-determined price range (Not arbitrary retardation when asked to set a price). Once the drop rates and quality of the items go up, there will a flood of similar items and not enough demand for it. Everyone will be happy in a month or two or whenever Blizzard makes a bad move again.
Honestly, though... the most fun I've ever had in Diablo3 was playing twinked out lowbies and just trucking through levels that I previously struggled through. Also, that invulnerable wizard glitch... I'm pretty sure everyone can agree that it was the most satisfying experience EVER. I was all "Honey Badger Don't Give a Sh-T!!" and just laughed manically out loud.
Yes, Blizzard has made a few mistakes:
1.) Aforementionedsszsss'ed ^ (*sigh, shakes fists)
2.) Ultimately!! Not immediately shutting down severs to fix exploits that kicked the living crap out of the economy since I guess every second up is more gravy!! Not that they can find the hemorrhaging right away but when you do find it... stop the bleeding (shut down severs) and make a patch for it (repairing the damage it's caused or the repercussions it might have caused). Think of us as money trees, for everytime you do something in hopes to make us give you more money think of the harm you're causing to us. We won't be around to grow money for you anymore if this keeps up!
Oh, forgot to answer the poll. Yes, it has become boring. My friends list went from 50 on d3 to 0 on d3.
