The only thing I will give you is the Occulus last boss on HM every time I would go on there someone would drop. It wasn't that it was extremely difficult it's that it would actually require coordination. Same thing as the old Steps of Faith in that gear doesn't matter as much and you have to do the mechanics correctly or it's a failure.

I do have to say that we need a variety of content like an Occulus type dungeon making use of flying mounts or something same dungeon design gets very old fast, and them making you repeat the same 2/3 dungeon for tokens is horrible.

Instead I propose that all dungeons should be synched to your item level making things equally difficult the better your gear is while also changing things a bit in how dungeons are designed (shortcuts, timed, extra treasure, optional extremely hard bosses, unique ways of handling bosses) and dungeons actually drop gear that isn't obsolete. These dungeons; however, should not be tied to the story or roulette.
