Teammates stay salty

So I'm a champ that needs to kite away during fights. I need to kite so my damage output can be useful but teammates say i don't do anything in fights cause im always in the back not dying or inting like they are. so end of game you can see my damage output is pretty high probably the highest but i still get flamed and blamed for doing it. I don't know if anyone cares about this but i find it toxic that im doing my part and yet i am blamed by my whole team cause im surviving for future fights incase we lose those teamfights. My damage is out there and i am fighting teamfights with them but still im thinking why am i getting blamed for it when im doing my job. im not that high elo but it kind of tilts me and makes me feel bad that maybe it is my fault.
