AT rules or consequences for abandoning team

[para.3458]

With the new AT format there seem to often times be issues with a member of the party leaving the group and making it so the remaining players are not able to finish the tournament and not receive any rewards. Just today somebody left the party after the first game because it was a loss. Then they stated, "and I am also not obliged to continue in the championship there is not even a rule that obliges me to do that" Apparently there needs to be a rule that if you sign up for the AT you will stay for the whole thing. I would love to see some kind of consequence for people like this that just leave the party and decline the next match.

Than they will just AFK with auto button pressed. Better to make ATs fun, than punishing player for leaving unbalanced matches.
