Good read Wobbles for writing this to us.
I think you forgot one aspect of the game : Mental Game.
It's the capacity of not getting frustated when you get comboed hard, when you do a bad move/bad call. The capacity to stay focus, to don't think you already won when you're up 2-0 in a BO5 and don't think you already lost when you're losing 2-0...
Mental Game is a very different aspect of the game because it applies to many other things in life and depend of your personnality. However I think you can work on this. I think practice a sport is very good in order to be able to stay focus and resist frustration. Meditation is also a good practice, it helps to stay focus for long period of time.
Middle match when you feel focus is gone, use respawn time or end game time to clear your mind and focus. Close your eyes, think about something else.
What I think is pretty obvious but a lot of players lose by getting frustated and being unable to focus.
I don't know if everyone will agree with me...
Excuse me for bad English, I'm not a native speaker.
Thanks Wobbles for your amazing post.
