So much toxicity?

I'm on my ranked grind, doing pretty well. I have a great early game jungle, I'm being super nice, the team is being a bunch of bros we're all friendly. I get us an amazing early game lead, then I try to kill the enemy soraka once, literally 1 hp off from getting her and died.

Team starts flaming..guys it's one death and we got a drag off it?

"Sorry my B I thought I could get her"

I initiate a teamfight, kill raka get their adc very low, my team was 1v4ing a riven, lost their adc and started to run away. Begin to flame me.

I secure elder dragon. Tell the team don't fight yet. I was 300g off my ga. Cleared bot lane, they started a 4v5 1 for 4 trade. Team goes off on me. I muted.

I somehow held our nexus towers against 4 people killing their lucian, riven, and running down their kassadin. Die taking 2 inhibs and opening nexus when team comes back up. We revive take baron, secure a second elder and end the game. Team still calls me absolute r%%%%% throwing the game.

What the hell did I do wrong? I jumped in on fights we SHOULD be taking. Every fight I engaged I killed their healer and made them burn summs. Nobody talked about MF missing all her ults, or naut ulting the useless lee sin. But if anything bad happens JUNGLE FAULT.

The enemy team was flaming the lee sin as well because I would outplay him.

Maybe I deserved it. But if people just stopping focused on the game as much as they did flaming we'd all be challenger.
