What Sportsmanship Means
Good sportsmanship means fighting the winning team. Many times you can wait for a mistake and come back, even when all seems lost. When you queue in you are making a commitment. Fighting on when things are tough is an obligation and a gift that you should be willing to give the winning team. They probably had more fun when you rebuffed several base attacks before losing. You probably would too if the roles were reversed. And folks on both sides may learn something. Think about it. I wish people would surrender less and struggle more. Yes, there are exceptions when people are being toxic, or feeding intentionally, but for the most part, being a good sport means fighting the winning team until they take the nexus. When you do that you make the game better and yourself more honorable. The people you play with are not your toys. When you treat them as such, you debase yourself.
I'm sure these things have been said before, but it bears repeating.
Fight on summoners and may you learn to value your honor and become a good sport.
