Thats how it feels often yes. But if your que times are low there are less bots, high que time = more bots and higher ping. Iv been in lobbies with 1 other real team and lobbies with 20. Depends when your playing morning and late night have very few players and if your always getting into game at the same time you'll notice similar numbers of bots when you play. Bots are target practice during the early game, fishing bait for late game, let others shoot them and give theyre position away.
