in-game communication

So played a ranked game, we smashed bot lane and all lanes, u know all good and stuff.

But then mid game comes around, brand and illaoi are pretty good around there, so i tell my team "lets not fight in small spaces because we'll lose"

no response... so i assumed they listened, .. p.s they didnt

every fight they wanted to take, was in the jg and we lost it every time and i would obvi back off since kalistas range isnt too high plus thats a nightmare for her to try and dodge tentacle while being perma slowed

and i just never really get why team never wanna listen, im not saying my calls are the best and u should only listen to me, but that time it seems like common sense..
