Stop doing this type of behavior whenever you encounter situations like this
For example:
Guy A picks Lux Jungle
B: Lux jungle? U kidding me? A: Well yea, I wanna try it out. B: Fine, then I'll go Singed ADC then
Like we get it. Guy A should not be doing this type of jungling experience if he were to want to win a game. Sure, people like him could be either trolling or were really trying. But what I hate most is people who noticed this tends to follow up as well.
Here's a tip for you guys. We understand what's going on, and we will most likely report the guy. But please for the love of god, DON'T EXTEND THAT TROLLING BY BECOMING ONE YOURSELF.
