Every Game Isn't Winnable, But That Doesn't Mean You Should Give Up
I just had one of THE most head scratching games I've ever played, and while it sucked, I lost, and it was just impossible to win, I learned a LOT from it.
I ended the game, as support with the most kills, most damage, second highest xp (no idea how), and 50 gold short of most gold on the team. I ended the game only with 50 CS so no I wasn't stealing gold.
The point isn't to complain, the point is, that game sucked, and there was no way to win it given how bad my team was, but sometimes you have to take those games and learn from it. The next game if I do that good with a few better teammates, I could win easily. Some people get behind and just pout, whine, and spam surrender and go right into their next game tilted.
Sometimes you have to suck it up and realize you are going to have teammates that have no clue what they are doing. It happens. I see too many people whine about bad teammates, and losing LP. Sometimes, you just aren't gonna win shrugs.
tl;dr Not every game is winnable, and that's OKAY. Learn from it, don't pout about it.
