I honestly enjoyed all of them, do I have to feel bad about that? One of them was less enjoyable, not saying I hated it or anything, just basing it on the concept this dungeon could have been much more. Maybe they run out of time, it's the first HW dungeon (lvl51) I think, after having leveled so many alts, you would assume I could remember the name but I can't :/ and my most favorite was and actually still is The Vault. I can't even count how much entertaining runs I've encountered, with people running straight into the horses, trying to kite horses, running to the other side of the map and die to fire aoe's, plain out refused of running the dungeon and just logging out at the last boss etc. Always a blast.
