I know that feel bro...
But to be fair, it is not always the ADC who complains. Everyone complains about how a support is playing...
Like the "ward all map" thing... Everyone thinks that supps are the only responsible for warding, regardless the ward quantity limitation...
I just had a game (Blitz supp) where bot was the only lane with a positive KDA and all turrets up. I didn't complain about anything like the bad (and only) gank, top, mid, and jg feeding like there is no tomorrow, people diving 1v3... Nor did Vayne, surprisingly... We knew that the game was over already but we kept playing...
So at the very end, we had only one inhib up, which I was trying to save from minions. Meanwhile the entire enemy team went mid 5v2 and killed both mercilessly. Top lane (5/10) then sent me "stupid blitz, you have just lost the game for us"!
Sure I did! 'Cause is a support thing to go 1v5 against a fed, dragon and baron buffed team, and kill everyone easily... Too bad I don't know how to do this black magic...
Post game chat, top harassed me again but one member of the enemy team said there was nothing I could've done because they would kill me anyway... At least some people actually knows how the game works...
