i agree and dissagree at the same time...
i would say these:
Albatross Dva - twin, synchronous machine guns set the standard for other German and Allied fighters. By the end of 1916, increased production of the Albatros gave Germany numerical superiority in the air
neuport 17 - helping end Germany's domination of the air war, the Nieuport 17 easily outclimbed and outperformed the Fokker E.III.
spad S.XIII - it was fast and powerful but difficult to fly. The SPAD XIII was flown by many of the famous aces including Georges Guynemer and Eddie Rickenbacker.
Pfalz D.IIIa - helped revive Germany's air superiority over the Allies. Compared to its contemporary rivals, the Pfalz D.III was not a great fighter, but it was very fast in a dive
so well get a german plane that cant dive, a french plane thats difficult to fly, a french plane thats pretty good, and a german plane that CAN dive.
would help make furballs more interesting
