How to be a great teammate

If you get a first blood, type in chat "gj". This will make your teammate feel accomplished in life and be a successful person. Ping the map if there is an enemy approaching, to warn your teammates of an impending gank (gang kill). Pinging is also a great way to communicate with your teammates, without typing in chat which takes time. Above is an image of a person who shows little tolerance for people who can't play the game properly (Vi).

Please don't be like Vi with a really rude attitude. It ruins the game for everyone, and including Vi's game.
