So Ive come to a random idea if you bother to humor me then by all means but its not
complex or crazy... Just hear me out

I've notice a lot of classes don't shine as strongly without having a good team comp so me solution is this

During CC start there is around 30s before the game starts
in those 30s they can allow you to change your class to what ever you have unlocked
similar to FL

I don't think this will break the game but possibly reinforce meta but it will also show if there is true flaws or benefits to a class that can't be notice as accurately without more prominent encounters
