Im finishing up japanese air and wondering what tree I should grind next. I already have the mirage f1c (not my favorite plane by any means) and have 8.3 for french planes. Almost done with props for germany and im rank 4 for Chinese planes. I could buy a premium jet to grind either as well with the upcoming sales.
France is very good I’m unfamiliar with Germany, but China has some excellent aircraft. Personally, I’d choose France, followed by China, but it’s up to you.
France its the best for air and ground battles. From those 3 options.
