Force ping test before starting ranked game?

Can you add ping check before someone start ranked game? My game is fill of people saying (as soon as we get into game) "OMG this riot 500 ping i can't even move, we lost guys gg rito" and i played 5 games in a row with ping stuck at 43 and never go up. So, it's obviously he have problem with ping but he started ranked game anyways. So, one simple check would be great to prevent people like that entering into ranked game.
