That's really just wallhacking and aimbotting - not really an AI as such. I wouldn't be surprised if there was a human doing the pathfinding with a 'shoot them in the head' button. If your FPS allows you to shoot with pixel perfect precision from across the map, rather than a more realistic 'in a general area', or if it's sending information that you shouldn't be allowed to have, then of course people are going to bot it. That's a hack/cheating, and should be banned, but it's more effective to make your game unbottable and not sending information that the player shouldn't know. WoW is not really that complex or difficult - maybe from a scaling point of view, but you just have to look at all of the clones that have sprung up to realise that it's not that hard. Botting there derives from wanting a shiny sword of whatever like my friend Bruce, but I can't be bothered grinding the same mob over and over for three months hoping that it'll drop. I play a game called World of Tanks which has a cone of fire mechanism (as you hold the gun still your accuracy improves), along with needing to take cover, work with teammates, help spot enemies, etc. Movement is also pretty slow, especially for the larger tanks. Bots in that game routinely get spotted and reported, not because they're headshotting people from across the map, but because they're shit - they're just not capable of the strategy or tactics required (eg. they'll leave fields of fire open, won't move when spotted, won't take advantage of terrain, will be out of position, etc.) It's a far more interesting game than "run around like an olympic sprinter and headshot people from the hip".
