i came to ask about the same thing. this has gotten really bad. i'm having trouble just finding any other human in a treeline game. the last couple of games have been me and five bots. they almost all have weird matching names like "Jane L Meek". short first name, short last name, middle initial, all capitalized properly. all playing the weekly free rotation champions. they don't even play against you. you can encounter all three of them together, while you're alone, and they'll just run right past you while you attack them. it's absolutely ruining treeline. =[
edit: i just played four pvp games in treeline in a row. all bots in every game. no one talks. no one shops. no one comes to defend a nexus. this game mode has been completely infested.
