I have to agree. Though, not everyone "leaves" because it's too hard or they don't know the fight. I have a friend, that will leave on PS in DR too, as a healer....and he is FAR from bad at healing. He just hates the dungeon and the fact that there's little to no reward for doing something of that difficulty level. When people do their "daily" they aren't looking for pain and suffering, they're looking to get in, get it done, and get out. This just rarely ever happens in PS, so people would rather just leave then sit in a dungeon for 90 minutes, only to fail because certain people can't grasp mechanics or are just incapable of doing it.
