LOL!!! Im so gonna do that!
Yeah, you need to actually down several teammates for it to ban you, or bomb three of your own hangers.
If your a second luitenent right now, youll level up fast. Just take a chute when you die to preserve points.
As for getting new planes, yeah, make kills and get coins. You also need to pay $5 for an upgrade, which you can do on the home screen. Once you get 3500 coins, which apparently you bought thirty times over, buy the Spad. Its the green plane with three stars speed and armament and two with one grey manueverability. Its better than the red fokker dr 1 because you can upgrade it.
dont worry too much about planes, tho. A good pilot can do the same thing in a sopwith as he can in the SE5A.
you improve faster in bad planes, too.
