I've been doing some research into the early German aces, who predominantly flew the Fokker Eindeckers from mid 1915 through to mid to late 1916.

All of them scored 90 to 95% of their kills before mid 1916 against enemy two seaters, very few victories against single seat fighters were registered. Despite the large and ever growing French and RFC fighter numbers in the air from the start of 1916.

From mid 1916 there are more and more recorded victories against Nieuports and DH2s (but far more Fokker losses too).

Clearly therefore, the early German pilots who lasted long enough to become aces, did so by avoiding fights against the French and RFC fighters if at all possible. However by mid 1916 it was virtually impossible to avoid enemy fighters and very hard to get away from them due to the performance gap between the Eindeckers and the entente fighters.

I think this would also have to be the tactic to adopt flying Eindeckers in WOFF, unless you want a very short and abrupt career indeed
