When I first made this account I had to play around 10-15 games in a row of scores like 20/4/50 before I even saw one human on either team. So many games of 9 bots it's ridiculous. Before anyone tries to claim they're just new, new players won't walk into the turret alone every time they respawn, those are either bots or feeders, either way they need to be banned.
After those initial games with tons of bots, the games after were horrible. It was a roll of the dice who would get more bots on their team who would make the game extremely imbalanced. You don't wanna know how many games I had to do 2 humans 3 bots vs 4 humans 1 bot, it's a terrible experience. Sure it worked out in my favor too sometimes, but it wasn't a pleasant experience to slaughter a team who was mostly made of bots.
Leveling up does help, but when you play late at night you are almost guaranteed 1 or 2 bots among the 10 players. There are still bots at higher level, they are just less obvious, but sometimes they will glitch and not participate in the game and just walk in circles/follow the human players and then turret dive, but they won't straight out feed like the lower level bots, but their behavior is extremely predictable to the point I can detect them pretty fast. But then you start getting matched up against strictly ARAM accounts and bots so the bots tend to stand out to me
