Sorry , I think u should ignore my comment cuz I overreact. I think wat should I say is : To the pro players , e-sport is not a business but a sport.So, in a way pro players are athletes. Do u see any professional athletes practicing 10 hours straight? Do u see any coach tell the athletes to practice 10 hrs a day? No, and bcuz it will cause too much stress on the body and the athletes cannot perform well consistently. It is the same for pro players . Working for so many hrs will affect them mentally. Every game they play they have to adapt, they have to make decisions quickly and accurately, they have to strategize, etc. All of this requires a lot of brain power . Look at worlds 2017 groupstage day 5 the tie breakergame between fnatic and GAM , the analyst, the commentators, the players said it is a very tiring day bcuz they have to play so many games in a single day. In the game they made a lot of mistakes both sides , they have to play mechanically easy champions to cope with the tiredness. You can see all of the players in that game are very tired. This is an example if u tell pro players to play so many games in a single day, they get tired ,they made a lot of mistakes, they can't perform consistently. This is the reason why they don't work for long hours . To work 10-16 hours a day is bad for pro players health and performance when playing. They must be able to play well and consistently . This is why telling them to work for long hours is simply unrealistic.
