Engines are too strong and reliable.

AI is way too good at spotting and keeping track of enemy planes - not only ace AI. It just happens far too seldom, that you attack an AI from below 6 and they do not twitch at exactly the right moment. And they seem too aware of anything around them - even at lower levels, and they seem to be able to look and lean in one direction and look to the opposite a split second later.
AI is more convincing to me than ever before, but it could IMHO still use some improvement.
