Aimbot draws in the n00b players and makes them feel like they are doing well. More players (even if they are n00bs) is good for Paladins. It's just about pandering to the largest audience they can. Yeah it's stupid and any serious gamer laughs at the n00bs who require aim-assist or aimbot attacks. Though overall it's good for the game, and if you actually respect yourself as a player you can just avoid using those champions.
