I'm asking out of curiosity and because I'm designing a game of my own and thought I might get some useful insight into why people choose to play this game over other games of the same genre.

I want to get into comp seeing as im about to hit lvl 20.But Its a bit intimidating seeing how good everyone is and so on. Any tips on how to approve and so on?Looking for coaching if anyone is interested. Edit: EUW BTW!
