Why are people complaining about grinding in an ARPG game?

So let me get this strait, the complaints I've seen about the game are; gem drops are too few, altars are too hard to find, rune drops are too few, bricking items while tempering is ridiculous, completely resetting masterworking points when resetting is ridiculous, etc. In the current state of the game, it takes 30-40 hours to consume all the content. There are an incredible amount of items dropped, which I think is a good thing. Mythic gear is too easy to craft, and a lot of things like that. What exactly do those who say that some things are too hard while the game is so easy and fast to consume want? Starting the game with a fully geared 300 paragon character next season? As I mentioned in another comment; bricking an item and looking for another item to replace it with is the only long-term content in the game right now. Of course, I'm not saying let's grind for hundreds of hours for an item, when I want to do that I go and play d2r, but I don't think it's right for this game to be simplified any further.
