I loved the old pre-nerf PS, but it didn't love how it destroyed DF groups. Almost always at least one member would abandon the duty on seeing that their roulette gave them PS. However I don't think this would have happened if the dungeon offered rewards that were worth the trouble (PS had the same drops as much easier to complete dungeons).

I too would love harder 4 man content, but I don't agree that it's rewards should be obtainable elsewhere, otherwise the majority of the community won't want to join in. We need to feel that our efforts are rewarded.
