Yeah, I guess as long as it´s fun, it´s not wrong :-)

D3 plays very different from D2. There are set items which give you insane power if you have them. Some sets only include 2 items, some up to 6 items and you get huge power boosts for specific skills when wearing as much of them as possible. As an example, the Bones of Rathma Set gives you a 9000% power increase for a certain skill when you wear the full set. Because of that in D3 your goal usually is to get a full set of whatever fits your playstyle and once you have it you are basically a god that shreds everything in its way. It gets a pretty quick game after that. So in a new season you usually try to level up as quickly as possible to 70, try to complete your set and start shredding mobs. Totally different to what you have in D2. I think that is the reason why some folks love one of them but can't stand the other one. They are very different.
