Change ranked role wheel so players don't get evil roles multiple times in a row

I'm thinking, should there be some kind of code written into the ranked role wheel that detects if someone was a mafia/NK in their last ranked game (if that game occurred less than hour ago) and decreases their chance of being mafia/NK in the following ranked game? Something that's like a reverse scroll that can only work if you were evil in the last game? I don't mind getting mafia/NK but it gets pretty damn annoying when I get those roles 3-4 times in a row.

I don't know if I just have bad luck but I consistently get mafia/NK in ranked games a few of times in a row and lose often before getting a town role and winning. It doesn't happen every time but happens roughly every other/third day. One of the worst nights was a couple of months ago when I got evil roles almost 7 times in a row and losing games before rage quitting as an SK and not playing for a couple of hours in frustration. Last night for example I got mafia roles 3 nights in a row - GF, disguiser, and the last one as mafioso which we only won because it was a 4 mafia game, surv sided with us, and town played abysmally.
