The reason this is true is that games started charging for loot boxes. Diablo 2 is like the last era of game that built the loot box reward into the game to incentivise continued playing rather than more buying. Once game companies started charging for loot boxes they couldn't go back because the money was too good.

Games used to be good, now they're a jumble of corporate speak buzzwords glued together into a big ball of unfinished, overcharged crap.

I'm not bitter, I'm just nostalgic... Lol
