Short version: Unlikely. The devs care about balance, and this would be much harder to balance then you think it would - if not downright impossible.

Long version: I dont feel like typing a long version today. Search the forums, this comes up frequently enough.

Final note...
I'm not asking for the level-sync system to be removed, since I fully understand why it's in the game. I'm just asking for it to be reworked so that it rewards endgame players more than it punishes them.
The sync system is in place solely to benefit the low level players - how it feels to an endgame player is irrelevant. The rewards you get from doing these sync'd roulettes are the part thats there for the high level players - and this is where low level peoples opinions are irrelevant.
