Rank game, sadly no champions to choose!

Hi Riot Games, during the pick selection of champions on a RANK GAME. WHY i can't pick or find any CHAMPIONS!?! Then i was queue blocked and then it is so depressing because it was about 30 minutes. C'mon Riot :(, and maybe soon I'll be on LOW PRIORITY QUEUE because of that. Please fix this Riot, this is not just for me but this is for the better, for all of us. Thank you....
