Fotm levels
something similar to what your asking for is coming at the end of january.

If my main fractal char is level 20 for example, and I decide to play an alt, I won’t be able to somehow benefit from having my main at that level at all – I’ll have to redo all those levels again…that’s my gripe about it.
The changes will make finding groups easier, but it won’t address what I mention here.
