No, the issue with the itemization in D3 isn't the fact that the RNG allows items with poor and conflicting stats to get through. The issue is that there is a severe lack of interesting affixes as well as interesting unique legendary items to aim for.
You're just bitching about the RNG because 99% of your drops are bad. People forget that this was an issue in D2 as well; high level runes and uniques dropped very very rarely. In fact, I would say that the RNG is a lot more forgiving in D3 than in D2 (due to the fact that rares can spawn with powerful affixes as well) and the tedium of farming/grinding is alleviated significantly by the existence of the AH. No one would ever claim that the itemization in D2 is bad and yet the RNG was more punishing in that game than in D3.
If there were interesting affixes added I would still be mad at the RNG that allows poor and conflicting stats to get through. RNG is the chance you get what you want when it's not a 100% guarantee. No matter what it is in the game.
In the past people were willing to grind more. Do you see how WoW has evolved?
If 99% of drops were shit in D2 and now D3 as well then it's because they decided the AH and RMAH was the way to combat hardcore grinding for many people. But they forgot the people who don't want to use either or hardcore grind. Which is possible is their most famous game. WoW. So famous for becoming more "casual".
Sorry this conversation has been drawn out so long, but, again, I know what I mean when I say it. After playing wow for a lot of the past 7 years, I find it insulting that someone wants to argue my use of the term RNG and my anger toward RNG.
Edit: I think I said it best when I said getting drops for other people for 200 hours and trash isn't fun. Why don't I like the AH? It's reliant on income which is reliant on good drops for other people, which are few and far between.
