You're really comparing D3 to D2, and on stats and itemization?
D3 stats - All on the items, instead of needlessly clicking a button 450 times to get some stats, you switch you stats based on what gear you are using.
D2 stats - JUST enough strength to wear the heaviest armor you plan on wearing, and the rest into vita. Every time. Boring.
D3 items - Even a really well rolled blue has a chance to be viable, if you are just looking for 1-2 stats. Legendaries, just like rares, have to roll good stats to be viable, and since the games only been out 2 weeks thousands of times more rares have dropped than legendaries, meaning nice ones have dropped. In the end you can use some legendaries, some rares and maybe some sets and be damn good.
D2 items - There was only 1 item to use in each slot, for your class. Any other item and you weren't near as powerful. Also boring.
Why the hell do people keep thinking D2's systems were better? They weren't!
