Because i play League of Legends for more the 2 years , i learned that trying to copy someone else is going to hurt you . You are asking yourself WHY now , right ?
Well , if you try to mimic the pro players guide and paths you will find yourself in the middle of nowhere. I always wondered why i dont play like them ( because you dont have the same mouse and keyboard NOOB !! ) . NO, thats not the answer.
The answer is so god damn easy , try to READ and READ more about heroes / spells . If you read everything about them , believe me you will find why are you ONE-SHOTED .
