Meh...The bots are there for the same reason the minions are there in league of legends...to farm kills so you can get closer to an upgrade (Titan). This is the first time a system like this has been used in an FPS so it feels weird to you or pointless. You nikkas complain about COD being the same every year and when a developer tries something new you nikkas want that old shyt back...make ya mind up. The game is perfect at 6v6...if you wanna play battlefield or ground war type shyt you know where to look.
Going back to the similarities to LoL that game is 5v5 with a lot more than 10 ppl on the map with the addition of different AI characters and the maps aren't small either. Food for thought. Stop playing this expecting COD or Battlefield.
I didn't play the game expecting it to be BF or COD. I just dropped my impression on the game after a few matches. I said its fun and that I'll pick it up. I have to try some other modes out some... IMO this game would be so much liver without bots and more players. I could see if the health model was high like Gears/Halo where the smaller player count meant longer fire fight encounters/battles... but that's not the case here unless your fighting in Titans
