A few more things you can work on-
One, most people seem to watch where they're flying, and take "quick peeks" to keep an eye on their opponent. Reverse that. Try to keep an eye on your opponent all the time, and just take quick peeks forward to see where you're going. Try to learn to fly without needing to look at the gauges too often, or spend too much time looking forward.
Once you've lost track of your opponent, it takes too long to regain his location, and you're losing ground for every fraction of a second that you waste looking for him. Lose track of the ground, and it's fairly easy to figure out exactly where it is again...
Two, go try the offline drone thing again, or better yet, the guys in the TA. You don't even need to fight/fire, just practice maneuvering all around them, never losing track of where they are, what they're doing, and what they seem capable of doing.
Personally, I like the F7 "Pan Mode", it makes it easier for me to keep an eye on things.
Three, start making an effort to base your timing and maneuvers, on what you see, rather than what you think is appropriate. An example is a basic scissors. If you're not watching the bad guy the whole time, you're not timing the scissors correctly.
You can take your eyes off your opponent briefly, and you'll need to, because he'll pass through bona fide blind spots. That's ok, proper, forgivable, as long as you know exactly where he entered that blind spot, what he's capable of doing while in that blind spot, where he'll exit that blind spot, and when he'll exit that blind spot (so if he doesn't come out when he should, you'll have a good idea of why, and what that means to you RIGHT NOW).
