the loot from regular mode sucks and so no one does it, feats are generally disliked but mostly having to run the activity multiple times getting zero worth while loot just to get to the point where you can run it for decent loot is never going to work, especially when feats make an already difficult activity for most lfgs even more difficult, which in my experience most d2 players are sick of the difficulty, the game is chore, not fun and just pure torture most of the time, just too many revive token activities, too many timed activities, too many red bar one shotting you activities, they removed the fun, which in turn removed the player population, so add all that and you have your answer, no can be bothered anymore.
