2-10 Mid, 5-12 Jungle, 3-8 adc, 4-8 supp. im a 5-2 top trying to win the game

how should i have gone about when the enemy graves is 1v1ing our supp lb thats died 8 times in the same way but doesnt care.

why am i matched up with people who dont care about winning. why should i be tryin this much just to win agame i deserved to win regardless. how do all 5 of them tryhard together and i get 4 bots running around headless.

can i get a "ur toxic so u deserve it" in chat please.

spamming "stop 1v1ing the graves as supp pls and play safer" didnt help

nothing helped. they dont care. so why the fuck are they in my game?
