Just played a game as an adc and all my support wanted to do was kill

So here's the issue. My support was thresh. We were facing an ashe and a wukong and I was mf. Thresh was very good at landing his skill shots on ashe and I reacted accordingly. But in the meantime wukong would kill me (although we killed ashe) this happened every time I walked back to lane. After the 3rd time I said stop I just want to farm wukong support is now 4/0/1. He is no longer a support he is a bruiser. Thresh left my lane and wandered around chasing kills while I was getting tower dove and killed. Unable to farm I sat at the tower and asked for a real support. My whole team flamed me saying I feed and stuff. I was 1/6/4. I continued playing. MY myself thresh laughing when I died and specifically telling the enemy team where I was to kill me. I then got a double kill by Ulting a random bush (yay me). I ended up carrying my team hard going 21/12.

I play to win. I don't let teammates die on purpose. If I have to flash in and use heal to get you out I will but what kind of person wants to lose because a player was upset with the way you play the game. Thresh was mechanicaly skilled but I never want to play with a support with that mentality. I don't think any adc does. So don't support if your going to Chace kills. Your job is to keep your team alive.
