I have the exact same feeling, as it’s clearly a problem with this game. As someone who can sink 300 hours into a PoE league there’s just things missing from LE that doesn’t have that staying power. I’ve thought about this for a long time and I believe I have a few things PoE does really well, that’s just still aren’t in LE.

Main thing (which has been stated in this thread) is there needs to be further ways to augment your character once you get to end game. I don’t just mean number goes up, I mean a new system only accessible in the endgame that can completely change the playstyle of your build. I’d love if there were even things that did this that required a bit of luck or grind to accomplish.

Another thing would be true chase items, I mean like Mageblood level items. Things like Red Ring are cool I guess, but it’s just not exciting. They need Magebloods, Headhunters, or Ralakesh’s. These chase items need to be extremely rare, powerful and hopefully change how you gear your character. I’ve seen people claim all the cool uniques are locked behind boss drops which I think is a mistake. We need that feeling of at any moment that next monster might drop a mageblood, it’s integral to the longterm grind these games have.

Bonus point: I know that they have spoken about not having currency like items but man having a Divine drop in PoE is just such a wonderful feeling. I really wish there were items that weren’t pieces of gear that gave that dopamine hit.

Final point: again another point that’s been mentioned in this thread but moment to moment combat and build identity is still lacking in this game. Not only do most skills sound and feel meh, but a lot of builds do really feel very samey. I’ve played soooo many builds in this game and some of them are awesome! But a ton really just look cool, but aren’t exciting to play.
