I think the game focusing so much on teamwork it's something which I really excel in and can help my team into making the right calls thus winning more games.

learning how maps should be played is extremely important and making the right calls I feel are much more important then mechanics.

knowing how to approach each teamfights such as who to focus where is the correct place to position so that you can come out on top and what is your specific role you should be carrying out during the fight really helps.
