I too see the CPU back pass and slow build up against me a lot. I saw this on WC and now on Legendary with modified Orion sliders. But I guess its also how I play against the cpu. I don't do the run and gun either. I also do slow build up. Only going all out if behind late in a game. I've enjoyed the game much more since using these settings. And I am pumped for 15 after seeing some of the AI changes they made.
