Teams

Okay, what if it really is my team playing bad? Like last game, i am Diana midd, vs Morgana, and i can't do anything to her, cause she was tanky, so i decide to play it safe and survive. I do, but while i do, my top and bot feed and ultimately result in a loss for us. No matter how much i roam, kill or try to call for objectives, they always do stupid things like trying to 1v1 a fed carry with a tank. No Nautilus can fight a Vayne 1v1!! But then they say i rage, while i actually say it very calm, not like this way :) Mostly i say: Hey Naut, you are a tank, you might want avoid 1v1'ing their Vayne. Then i get reports. What to do if my team really sucks? Or at least, i can point out all their mistakes?
