Yeah, buy the albatross. Theres two teams, german and allied, as you know, and you want the nuiport and the albatross so ur okay on both. However, at rank six, youll actually get better faster in the planes that you SHOULD be in, the spad and the red fokker. Or, i use the camel and brown fokker sometimes, and so do plenty of aces. Use the lower planes, thats my advice. Not paying for the credits is good for you.
