I doubt you’d devote resources to making changes to D2R if you ran Blizzard. It just isn’t enough for the, probably, 10,000 remaining players. In the decades to come, as more and more of the remaining players die (I know, morbid) the game won’t have any players. Its not attracting new people. Barely anyone under 40 is playing.
I have talked a few of my younger friends into buying it, because they’ve never played it. None of them kept with the game after a week to a month. Their feedback was the same thing I’ve been criticizing for years. There are just too many systems that deter them from getting invested.
Drop rates are too random and too infrequent. They can’t target farm specific items and they don’t really want to engage in a trade economy. They like trade, in that they’ll pass an item to me, or I will pass items to them. The difficulty spike of hell with damage immunities made them not want to play, at all. They didn’t want to overcome the challenge, or even do the META and skip entire areas.
