I gave up on Diablo 3 fairly early into its release. The biggest problem for me was always the loot. I never, and I mean never, got a good drop I could actually use on my main character (Demon Hunter). Sure, I looted some stuff that was good for other classes, and managed to sell a lot of it on the auction house (both gold and RMAH) — but every single piece of gear I was wearing was acquired from the auction house, not from killing monsters.
Diablo is all about the loot hunting so that’s probably why the game barely lasted more than a month for me. I decided to give it a go with the recent 2.0 patch and let me tell you — the game is about a thousand times better now. Loot 2.0 is fantastic. I am getting drops I can use all the time. It has recaptured that feeling I used to get from getting new loot in Diablo 2, only now it’s even better. When I see a legendary sitting on the ground, I know it’s going to be good.
