Champion decision

Hi Riot. I have the greatetst idea. After that u mede the new champion slect I'm just wondering why dont you also make something like this for exemple I choose mid and I can choose ONLY MID champions the same as other lane s because I'm literallly feed up already from the start because I've been seen too many people torll like for exemple Gnar support, Blitzcranck jungle,Yasuo adc. What am I suppost to do play League of legends and having fun with it??

Thank you Riot What do you think guys about this Idea should they make it something like this??
