since the past week following the most recent 3 patch updates, the file which contains that setting has not been changed by an update, and it does not appear to be any different than it was before based on the last modified date of the file. I noted this on another matter today when I added links for the prdemo files tracker files for the "replay" button in PRSPY.
I'm not sure, but I think @=VG= m823usraised the bots dificulty about 2 weeks ago. I don't know if it was put back. but i have had the same experience that bots are very accurate and that in places you hardly have a chance. in general, i also have the feeling that there are fewer bots on almost all maps or they chill on the last flags and you only have contact with the enemy towards the end. So generally less fighting but harder maps.
