I am sure most of you have had the experience of playing 2 maps without a single Traitor round, and there is a semi-solution that i thought the server can implement, it is to change the generator from true random to pseudorandom. For those who don't know what psudorandom is, say the chances of being a T on average is 1/4, if you didn't get T on first round, you chances of getting T will increase on your second round, and if you still don't get T by the second round your chances would increase even more. So every consecutive round that you are innocent the chances of you being a T next round is higher. So the chances of having huge innocent streaks are much less. The average T amount would still be 1/4 at the end.
it might let other players know hey this guy hasnt been T for a while and so they start following the player nonstop watching his every move etc, wont really help the player to kill the T but the formula might make it obvious to players and increase suspicion to a high extent
I'd just buy a traitor round to be honest. I've had experiences when I haven't had it for a whole map at most. (Lucky at most I guess, didn't know you couldn't get one for two maps.)
realistically speaking it will do nothing except having a chance to overlap the t rounds. Yeah most people will get some really unlucky streaks quite often
