The Savage Coil is a bit wat you want. Hard, repeateble, no lock, a challenge.

The difficult part is making an unlocked difficult raid content like the one you want that people will take the effort to do, and that does not give too much loot so that people that play a lot don't get everything too soon. If it does not give enough loot it is likely people wouldn't want to take the effort. It might be they introduce some content like this in the future, a non-locked Coil with a very low drop rate. It may be discouraging to beat a difficult instance and have nobody in the group get any loot, though, and only from time to time somebody gets a piece of good gear.
