Not sure whether this has been mentioned (too lazy to read a 1000 posts

Offline play:
I notice that on all Ace settings 4vs4, when getting onto any AI opponents tail, it's supporting number will be onto me if I don't hit my target on the first pass.
At the same time I ask my #2 to cover me.. he's nowhere to be seen ??, even after minutes of dodging the covering opponent.
Summary:
Target AI are able to work as a team more than your own AI = No good
This is not random, but every quick mission set.
