How about we combine ideas? All the hard stuff you want is the equivalent in difficulty of ultimate, but the rewards are the same as normal NMs.

You get your difficulty, but no actual advantage.

Oh, and normal mode raids are NOT the casual version of savage. When people want the best gear, there are 2 ways to get it: savage, and relic. Savage is really hard, relic is a huge grind for the people who can't do savage. In the end everyone gets the same ilevel gear in a different way.
