I just had a champ select with 3 disco champs

A ranked duo wanted to force my team to dodge for no reason so they told everyone they were trolling before bans even started and then both picked 'disco' champions. Then a 3rd guy decided to join also and took another disco champion. I dodged and lost LP and they get what they want.

Why is there still no way to punish this crap? Why am i forced to lose LP and my time when i get queue punished?
