Please take a look at LOTRO for the proper way to design end game dungeons
Dungeons as of now have zero purpose end game. In fact, anything other than hunts has zero end game purpose. Good luck trying to get Ramuh Ex cleared. Why bother? The hunts provide better rewards for a fraction of the skill required.
They need to take a look at LOTRO for proper ways to design end game dungeons.
Basically, every end game dungeon in LOTRO had 2 difficulties. The higher end difficulty also had an optional challenge on every hard run, which when beat, yielded very good loot, just a little under raid gear. Difficulty was on par with end game raids if you chose to do challenge mode.
I think what this game needs is to have a similar system. Savage mode for all dungeons with additional optional objectives. The problem is that it's still easier to do hunts and get better gear, which is why hunts were a mistake. Hopefully in the future they can overhaul the gear progression to be more gradual.
