metagame

i am not the best player so i'm sure my opinions arent worth much here but it is getting boring playing with/ against the same tactics every game. top and bottom lanes are identical so why does nobody play support on top? or solo a good ADC counter on bot and let their support roam or support their fighters tank or mid? do you even need a jng every game when herald and drake are on the top/bot river? yesterday i played a game with ~~some idiot ~~ our support saying he wanted to be the mid so we played jhin+heimerdinger vs a yasuo mid and the whole game was no contest.

there are no reasons roles and peoples ideas for them are so narrow.
