Please don't play rank if you arnt ready to support if you have to
Not even in bronze should it be acceptable to have zero preparation to support if you have to, but in gold ( and this isnt the first time ive dealt with this ) I just had a match where I went support even though its one of my last roles, for this other person to go mid, because he didnt even OWN a support champion. He even went 3/14 and was doing a great job to put the team on tilt with his attitude as a gift to me.
When I told her to stick with the team in bigger groups instead of dying in random spots across the map alone or with just one teammate nearby, her first response was to snap at me at how I have died aswell after doing risky things, while she had 2x more deaths caused by risky actions, and 2x less assists than me.
