I need tips about LoL

Farming is the most important then focus on objective, don't throw 20minions = 1 kill

Go into a training mode as Annie and just practice last hitting minions until you can get 120 cs by 15 minutes. Then go into games and only fight when you have a level advantage. Half the game is farming but you also gotta deny them their farm.

Be a good guy and have the right mindset. If you work with your team and talk to them then you will succeed.
