Disclaimer: when I refer to D2 players, I donāt necessarily mean players that still play D2 or even that have ever played it. Itās just the type of player mentality that enjoys that game. Just like there are D3 players (usually referred as casuals) and PoE players (usually referred as traders harcore).
All ARPGs since D2 have been āimprovingā on it. Sadly, it never worked because D2 players donāt enjoy it as much. What games have mostly ended up doing is simply aiming at different types of players.
That isnāt what D2 players want, though. They want to grind without results for hours so they can get that huge dopamine hit when something great does drop. Getting constant small improvements doesnāt deliver dopamine, itās just a āmeh, I gained another tierā. Kinda like āmeh, I gained another paragon levelā.
This is something PoE had initially until they shifted their whole stance to currency. The only drops that matter these days are currency ones, whether itās divines/mirrors, div cards, etc.
Again, this highly depends on what you consider improving. D2 players like attrition. They like grind. They like that huge slow buildup to the dopamine hit. Take that away and these players will become bored and uninterested.
You can have improvements on non-gameplay QoL, like stashes, loot filter, etc. But if you start to implement too much QoL on gameplay systems, like legendaries, that detracts from the fun these players have.
All of this is not a bad thing. It just depends on the players EHG is aiming for. Ultimately, there are several types of players and many of them are incompatible. You canāt make a game that will please all of them. D4 tried and failed miserably at that. So games have to decide which type of players they want to appeal to.
So far, LE is far more appealing to D2/GD players than to D3/D4 ones and even to PoE ones, though theyāre closer to them than D3/D4 ones.
Bottom line is that there is a significant number of players that enjoys the grind. That enjoys having near unachievable gear and goals. That enjoy long stretches of no good drops/craft just to have a huge boner when they finally land a 2/20 or a Tyraelās might.
And these players get bored with a game the less grind it has. For example, if you make 4LP gear easy to get (even though you donāt actually need LP gear), they will leave. Because thereās no hard to get goal.
D2 players donāt like NGU (Number Go Up), they like slot machines.
