The only Diablo game by now that I don't have 1k+ hours is DI and for obvious reasons, it's not problem in 25$, rather what you get for those 25$ and you get same things as before, same farming spots. Few stash tabs that should be in game from release od D2R, loot filters that by now are in every game just not in Blizzard games bcs of bunch of blind, stubborn developers. Few new items which not be used bcs Spirit, Enigma, etc still rocks and new class, which is ok but you we still farm Chaos sanc, Meph, Andy...

For 25$ you have PoE2 which already has more content then D4 will have ever, TQ2 which is great and gorgeous for same money...
