We've already gotten those end-game items that make the Vicious dungeons reasonably doable. Things like WHUPAZ, Elite Items, and the Alchemist weren't around when those dungeons were first added.
Then again i find it disturbing that i was able to complete dragon isles relatively fast and almost won namtars lair while I'm still not able to do the witchs quest pt 6.
I'd like to be able to do at least all quests on dungeons of one difficulty before moving onto the next difficulty.
Also, I think this quest is seriosly broken because it is the complete opposite of the central concept of the game:
Having meaningful decisions.
I don't think it's meaningful if I'm locked on class, diety and strategy setup for this to be winnable. Not even considering the luck you need in order to get all you need at the beginning. I just spend all my money (~5000) on preparations for this and don't really feel like playing the game anymore because it's just depressing and feels unfair. This is the part where it changed from strategy and skill to complete luck, even if you have figured out how to win the dungeon...
