Like any game, especially continuing a series like Diablo, you will find players that want it to be the way they envisioned it and get upset when the actual game does not meet those expectations. It happened to me with D3.
I simply stopped playing D3 and moved on to another ARPG that I thought was personally better and gave me either all I was looking for or at least more than D3 did.
It wasn’t until D4 beta was approaching that I caught D2:R and D3 Xpac on sale together that I played it again and I found out that the hate I had for it was not warranted. The QoL changes over D2 were actually very nice and not appreciated by me at the time.
I’ve played since D1 and looking back over all the games, I have to say the QoL changes with each game make me appreciate them far more now than I did when they released. QoL > nostalgia is what I’ve learned. I do miss unique things from each that are currently missing from D4 but they always can be added. If not than it’s fine. I’ll deal with it.
To each their own.
