+1 for have a smoke
I strongly think this is something you can just control mentally. Just think, whats the point of getting mad? It won’t change anything, and is more likely to just make you play worse. Furthermore, what difference does it make if you lose? There’s nothing on the line online or in casuals. Even in tournament, the only thing it accomplishes is making you look like an ass. If you’re having a night where you are playing bad, just re evaluate why you’re losing, and change it. Make adjustments. It should be a learning experience. Sure, there are people that play in an antagonistic way, but its not worth getting worked up over.
I remember once when I was in this super training mode over the course of a couple months really trying to get better, and in a tournament I lost to someone from judgment (3s mechanic that decides the outcome of a double KO randomly), and I was so heated. A little while later I realized, why get so angry? All it does is make my opponent think I’m a dick.
