Level Syncing isn't the best solution

[Rhomagus]

There is also the fact that low level dungeons are not designed on the idea that you have a full high level tool kit.

They weren't designed with the stats on high level gear either but they created a system to adapt that didn't they. They even found a system that completing replaces the visuals of said gear with other gear but maintains the stats. The proposal is far from impossible.
