Dungeons are there mostly for Bosses , now heres the problem, who really cares about Dungeons except go to Boss and farm items ? I dont think anyone care ,until you find the entrance to boss.If you die on Boss is extremely boring to do it all again plus when you die you dont respawn in Dungeon entrance ,something very annoying.
Dungeons needs to have purpose and meaning or become smaller and faster to go to Bosses because dungeons by themselves are a little bit of irrelevant
Personally I don´t mind. For me dungeons are a way to get ressources. Otherwise I have to do the boss and go somewhere else for gold, shards, keys, and whatnot. While Im in the dungeon it better be useful imo.
