As of recently, bots have begin to fill up for player slots in the Conquest gamemode.
The problem with these bots, however, is that they don't actually do anything. They stand idle with a select character to most likely farm proficiency points (i think?). By the end of the match, you would see them with 0 kills, 0 damage, 0 assists, and probably a large number of deaths.
Conquest is the game mode that I and some other people use to grind proficiency. I hate to see it get infiltrated with bots that just flood up the lobby to do nothing the entire time.
