To level up to 30, just to announce you're gonna feed with that account.
Yeah, i just had to dodge a game in which i had such a guy in champion select. I checked his profile before dodging, it was freshly dinged level 30, and he said that he's only going to feed with that account for fun.
Like what? And his summoner name also indicated that "i just got banned on my main" , i'm not going to say his name here because shushush , no witch hunt.
