Last Game

I was support and our Ezreal was complaining that I was taking his CS. I had so obviously I'm going to last hit one or two minions once in a while but apparently this Ezreal didn't know this and kept on telling me to stop taking his CS. What should I do? I was really annoyed at how some people don't understand that a Relic Shield means that both you and the support will get gold. He was also blaming me for not helping him with an ability when I was too far away.

I muted him in the end but he was really annoying me at how to play the champion I was playing. I was trying out Tahm on my PBE account to see if I liked him or not (and I find him so fun) and he was telling me that I can press R again to send myself to the destination when I was ulting (I know that and what this champion does) and he seemed to think so highly of himself and that we should always save him no matter what. He kept on criticizing on what I was doing and how I should be doing it. We won the game but I just wanted to flame at that Ezreal so badly, I didn't don't worry.

What should I do with these really annoying stuck-up ADCs? They put me off so badly, I can only mute them but is there ANYTHING else which I can do?
