freaking LP loss after team sucks balls

i am so fucking sick of being pretty fed or just doing really good in lane and the whole game but the fucking team sucks and just feeds and is totally useless like they dont have a fucking brain.This has been fucking happening to me a lot lately and this is so fucking frustrating.Riot should make it that u lose less LP if u did good but ur team sucked,this shit isnt fair because its not enough that we have to play with trolls,inting assholes etc sometimes but we also lose the fucking same amount of fucking LP,its not fucking fair.Riot please fucking do something about this shit come on,this happens way too often to everyone.
