Concerning the outnumbered thing thing, knowing the limits of your ship and coordination with your teammate can net great results. Concentrated fire is rightfully common. However a Junker with three engis in full repair mode can be a stubborn enough beast to allow for an excellent distraction. Sometimes a 2 v 1 isn't just about escaping, but simply living long enough for your team to take advantage.
Concerning communication, as pilot spend some time talking to crew. On many ships (Junker and Pyra come to mind) battle stations are important and everyone has a job. Don't assume the importance of the job is self evident. I have found that after explaining the importance of the chain gun in armor destruction, suddenly my chain gunners are a bit more accurate and focused on the hull. Don't just say what to do, say why to do it.
Recognize success and shortcomings. Just don't be a Dick, unless of course it is followed by Tim and you are of noble heritage.
