Ranks games

hey how are you there well , my problem in LOL its the rank games the rules in champion select : if you leave you will lose points ok here the problem every one knows and you know the bans are important and when the people select their champs are important , so many people they are doing bad and they saying we will feed and thinks like that or they not answering .... However , whats my fault to play this game and lose ,and i know I'll lose but i cant exit because the rules , so please give us a choice to exit, its rank not normal , we need that choice to exit and to get a good team with out losing anything . i hope if they can do something about that .
