It can still be fun, but good luck beating it on Advance difficulty or higher with them, they're just not competent enough even when they have aim-bot abilities.
(there are no means of issuing orders to them, which is annoying as they like to waste med kits)
L4D for me was more of a social-action game, I need the mic spam of "FUCK FUCK TANK, GET BACK!" and teammates yelling or oh-shitting when shit hits the fans, or dominating the other team in Versus mode.
