I think what's being lost here is that the idea behind this post was to get 4mans to start pushing towards savage mechanics. Within the game system, you can introduce difficulty within doing savage stuff. Quite easily in fact. I'm saying this from a non raider perspective too. Again, within the game engine, the devs can easily make an entire dungeon nerf healing and tanking through persistent debuffs, just lower the damage that mobs do overall.

I would love to see a gimmick dungeon that is like ff9s Ipsen's Castle, in that lower ilvl makes it easier to actually get through the dungeon
