Lately I've been joining in an empty server waiting for people to join. Slaughtering the bots of course... but, there are times I see regulars playing against the bots and when I join they leave =/
Make the bots harder so people don't improve their ranks etc with just bots and not play against people. Also, I like a challenge, so harder bots would be appreciated
Just take a look at a few people and you'll see the skill shot up an insane amount. Hell, even my rank went up cause of the difficulty of the bots.
