Random Modes Legend of the Poro King (exploit)

Just thought riot should know and/or make this in-feasible. Blind pick on legend of the poro king people random this week...people deciding to leave just before it enters matchmaking when they see a team comp they don't want to play against.

I don't mind dodging during the picks but not literally.. right before we load to avoid playing against the comp. Hoping that will be patched so people can't exploit the hell out of it.
