I agree that it remove some fun when your teamate dont want to learn or take advice. such as pushing/extending to much, 1v2 suicide, no help with team fights etc etc... Especially when you ask them and they keep doing it.
I found that, when I stay polite and good manner, it end up ok with these kind of person.
Personnaly, I wouldn't queue with them if your planning to have a good game or a ranked game for instance. The goal of a game is to have fun, so as long as you do have some, who cares. But if you want a serious game, it's another thing.
Im far from a pro and it's not my goal to become one. But Im sure able to help others and able to receive tips from others to. Even if most of the time its like OMG STOP FEEDING YOU FKIN NOOB at 0-1 XD
