Well my experience of super AI consists of the emeny just getting much more proficient at killing me & my comrades, while my squad (in sp) remain, er... as mentally challenged as ever.
Example of *seemingly* dumb (super) AI: When playing the Oil War mp mission, my AI controlled AT team mates ordered to target a vehicle, really annoyingly refuse to declare "Ready To Fire" until the target is about 10m away! (slight exagoration) -even when they have clear line of site!
