In my experience most players do not really behave 'tactical' (ie as a team). Only clans do that where humans have specific roles in the map. Its like humans playing according to a script:
head to spot A
guard bombspot B at location x,y,z
etc.
On the public/clan server i play on (see website) i found most players just react 'logical'. They try to vary their paths (mostly on trial & error) and then concentrate on sounds. My recent changes on the bots already showed that bots that care about sounds (and who will hunt them down, with noise or without) already gave the feeling that you have to be carefull and not a dumb Quake like player to shoot everybody. COmbined with the GOdLike skill you better be quiete if you EVER want to make a chance
