I don't get people watching Overwatch or Dota matches rather than just play the game themselves.
And since someone will bring it up I don't watch sports events either though at least there is the argument that I can't just go out and play football or race cars on a whim like with games. :D
I found that the korean pro OW games are pretty easy to follow. They tend to have a blue or red outline around everyone on a team. At a given moment they are following 2 players, one on each team. One will be the main screen and the other will be a smaller screen in the corner.
EnvyUs is a top team right now, so strong and dominant, that everyone else is just fighting for the second place. So they just have more room for experiments.
Mhd Ali beat heavier top class opponents by practicing his full arm length punches. You dont do that to pro's because its a slower punch and they're pro's but thing is he realized that meant they would not expect it and had not trained to deal with it. It broke their over-trained strategy.
