People have complained that they dont like when good players tend to get really high scores because they find these noob lobbies. So my solution is to have so that levels 1-50 can play in any lobby they want (prestige 0), but once your prestige you can only play with prestiged players. Knowing how easy it is to get prestige in this game, it should defintely not be a problem.
Also, they could have an option for newcomers which will allow them to play with prestige players but by default that option will be turned off (This is for people that remake their account, or join game 1 year later when not a lot of people are playing).
Also, in the beginning it will be hard to find prestiged lobbies (since not everyone would have prestiged in first 5 hours) so this feature will only activate once x amount of people have prestiged.
Btw, if someone scores 10K, and rest of lobby scores 4K and all of them are prestiged, then I dont feel sorry for them at all because once you prestige, you should at least have some idea on how to play this game and not get destroyed every time (like in ACR - people have prestiged but not gotten any better, one of the reasons is smoke bomb).
Your thoughts? and do you have any better ideas?
