No. I do not agree at all with the OP. If anything, maybe have seperate dungeons. And just have some dungeons that are a decent challenge, some that are hard, and some that are /ragequit hard. Its hard to have any fascination or awe or "legendary" feats about Absolute Virtue, if he has an easy mode. So I am not against there being normal, hard , and elite dificulty dungeons, but I prefer then to be seperate events.
