This is pretty much how I feel. I want to discuss the purpose of the bots, and the ramifications for them being in a presumably competitive multiplayer. Most people don't like responding to these questions though, they'd rather this thread only be about the 6v6 player count.
I think this might be the fundamental issue. This is not a competitive MP game. This is a MP game wrapped up in SP like scenarios where players get put on each side to achieve the outcome. Its not straight TDM where the person with the highest K/D ratio wins.
I think the A.I is there to help players feel like there is more than just 12 players running around killing each other in CoD styled maps.
