Coming from the same vain as games with "roguelike" elements, it would be interesting if each week SE had a predetermined dungeon layout that could be done solo or in a group.

Basically the dungeon would be 10 floors start at max level but with certain restrictions like Half HP, Mobs STR doubled, Double Bosses, Blind leading the Blind, Trapper's Delight.

The idea would be you enter the dungeon and the 10 floor layout would be the same for everyone, and people could have up to 3 attempts to get a high score for both solo and group attempts. High Score for each week could get a reward, maybe accursed horde chest, potsherds or even unique glamour that only comes from attempting the weekly run.
