Some people either played d2 after lod or after many patches. (or have rose tinted glasses) d2 was far from perfect for quite some time. I am liking d3, I don't have borderlands 2 or torchlight 2. I am welcoming these changes.
D3was far more bug free than d2 on launch. I remember the save game eating bugs. I might be lucky but d2 crashed more times for me (losing loot) than d3 has dropped or crashed (I'm not sure it HAS crashed for me yet in my 200 hours).
D3 is not d2 and was never going to be d2(lod) with new graphics. Sure it needed more on launch but in a mere 5 months it is a different game. What do people want though? It isn't like you a pay a subscription.
Variety is good and post release support and patching is also good. If you don't like it play something else, and I just don't understand (short of trolling) why people jump on the same argument about d2 every time
Never argue with an idiot. They will drag you down to their level and beat you with experience.
