Don't do it.
Do you ever find yourself tryharding harder than that time you spent an hour on the toilet bowl pushing that stubborn turd out of your a s s after 1/2 off taco night? After you spend 11 minutes pushing on your hard scum fos to the point of having an aneurism, only for them to get hammered and flip blue, or worse flip PR.
Accept the fact that you can't scumhunt for sh*t and that your reads are always wrong.
Find a townread and sheep their reads. You'll win more games.
Townhunting is more valuable than scumhunting.
When you're stuck in 3 way no clears, do not rely on your godsent scumhunting talent because you will surely mishammer. Instead, consider the reads of all confirmed town who died.
If you sheep a townread and their FOS always flips town, your townread is mafia OR you should dodge them because they suck OR you should stop playing ranked mafia because you suck.
PSA: Unnecessary bussing does not win you games ever. Bussing is scummy. Do not do it.
