Pretty much this. I do miss the old dungeons a bit, but people were just as dumb as they are now and made some runs unbearable. Hunters jumping into the arena with pet out UBRS pulling tons of trash, getting statues right in ST and people getting lost "fixing the problem, paladin/lock mount quests, ugh, not to mention how long it took to clear these places..
I'd like to see xrealm gone, but LF-tools remain alongside streamlined dungeons. Maybe I am just getting too old, and I don't want to spend my entire session in 1 dungeon, sure is nice not having to play overtime to get shit done.
