In your opinion.
Wait, you
didn't max out Warmth? Next thing you'll tell me is you didn't max out Increased Stamina.
This was my experience with D2 as well, but sadly I lost all my old characters (84% grail!), and while I have a current copy it's not the same anymore.
I think the QoL changes that would make it an absolute smash would be a shared stash a la D3, and more space a la PlugY. I'd love a Charm holder, or if they were all 1x1, but then they'd need to normalize the affixes and that sounds problematic.
I seriously think the best way to give us an updated D2 would be to allow a new game mode in D3 that plays like D2, because D3 is visually awesome and it already has all the QoL we'd want, but instead give us a real loot hunt, rework treasure classes for certain areas and bosses to recreate the old feel of Meph/Pindle/Baal runs.
Lastly, a few people were commenting on runewords, dupes, cookie cutter builds, etc...for those of you who played on Bnet more or less exclusively and lived in a world of Enigmas for all, you can beat the game, and do succesful MF/XP runs, with way less than that; you may not be as efficient, but it isn't impossible.
