Why do you even Surrender? (In ranked)
Almost EVERY SINGLE GAME, can be one, unless they are in your base with baron, dragon 5, and 30 kills above you , you can still win. Every game can be one.
Don't play ranked if you aren't willing to put in the time an effort, just because were down 8 kills at 20 Minutes doesn't mean we lost, this is SOLO QUEUE, players aren't coordinated enough to win the game quickly, they'll run around getting kills or just split push without taking a lead. You can come back on any game and every game. If you have to fight it out till the 50 Minute mark so be it. And if thats to long of a game for you and you find i boring, go play some bots or normals.
Ranked is a Mode for people who WANT to win, and WANT to put in the effort to become better, you quitting at 20 Minutes in because Little riven over there fed 5 kills. Isn't gonna make you any better, always play a game till the end or you will never learn nothing. You'll just keep being the Bronze V rager, who thinks everyone else is to blame.
