It would be cool if once you reached the highest rank you would git to airplanes each the same as the se5a and albotross but with upgrades in manivurabilty one star upgrade in that so max manivurabilty would be for and a upgrade in armory to give it five in stars in firepower. The to planes I would suggest would be the sopwith f.1 snipe and Fokker d7. This is just an idea I had on my minde not somthing I think should absolutely be done. The sopwith f.1 snipe was a plane made very similar to the camel but got a bigger more powerfully engine and did some changes to the wings the top wing is a but lower and curves down like the se5a unlike the camel curved up frome what I read it was done this way to make the plane less deadly to fly becuse the camel was as deadly to the pilot as the enimy it was fighting against. The Fokker d7 you all should know about as it was known as the best plane of the grate war and could almost hang on its prop.
