I've been playing with bots on normal to hard lately, and they seem weird. All the bots on your team suck REALLY badly, the bots on the other team are able to see you, and headshot you, through walls, and are able to headshot you while running. All in all the bots, on normal (before it was really easy) are able to win so easily its not funny.
This update has seemed to ruin the game for me because all i do is play with bots because of my bad internet.
