How do you normally react upon losing a game ?
For me, it depends. If i lost really convincingly, then it would not have been too bad honestly. Other than that, when a lost is due to a frequent pattern which i could not counter or no answers, or when the loss is by a 1% life, most of the time i will feel angry with myself, disappointed and even thinks about quitting the game for good and go play single player games.
After a few minutes or hours, that feeling slowly goes away and i compose myself for the next battle.
