IT MAKES IT SO YOU CAN USE CLASSES YOU NORMALY DONT USE

It has always been in tf2

You have the option to do it yourself but it would certainly make things interesting if every so often a match would choose a class for you and you had to stick to that class throughout the match. I would like it but I think a lot of people would just quit the match so it wouldn't work
