Griefing/Soft Inting
Likely to get down voted to hell, but this is a trash account anyway. (https://na.leagueoflegends.com/en/game-info/get-started/summoners-code/)
For those of your who aren't aware, League of Legends is a competitive game. I've played for nearly 8 years and there has been a progressive decline in the competitive nature of this game. Sadly it's also corresponded to an apathetic community that no longer calls out griefing behavior. What's worse is it seems to be the social norm for the opposing team of the griefer to troll any of their frustrated team members (bc f#ck everyone else).
Inb4 people argue this topic is subjective. Clearly when we are discussing complex strategies our opinions of most effective tactics will likely diverge. Clearly people are going to have bad games. Clearly new players are going to do stupid stuff. This is not a flame post. I am not suggesting any of these things.
When a Plat 5 top laner has a vision score of 3 at 15 minutes, he's too drunk/high to play and is clearly f#cking griefing.
