I understand that they are basically mooks you kill to make yourself feel badass. And I still think it's a stupid design choice. It worked out like this, believe me:
16 v 16
Requires huge map, system can't handle
12 v 12
Requires big map, system can't handle well
6 v 6
Small map, works fine, but feels like too few players
6 v 6 + mooks
Small map, works fine, shit to kill here and there -> Let's go with this.
I won't spend a penny on this game.
Why would I believe you over the developers of the game that have showed AI from the debut?
It makes no sense to suggest that the system can't handle that when you said it yourself at how impressive looking you find Battlefield. When they were IW, they deserve more credit for what they did with CoD, catering to 60fps on those consoles meant they were one of the few people focusing on playability and fluid response.
