Technically it is possible to buy ur way to top tier.
How you may ask?
Basically you get convertible rp by unlocking modifications for vehicles. You can also buy them, that still gives you convertible rp.
So you can technically buy a bunch of marketplace vehicles and buy all modifications until you have the desired amount of convertible rp, with that you can just convert to top tier.
So technically it’s possible right?
But no one will ever do this because it’s just to expensive.
Brother the F-4S identical as the F-4J it just the premium version, P2W means when the buyable velchie better than the tech tree variant but in this case they’re identical so it’s not P2W to spend money on a jet identical as an another one.
Ohh damn, I have the F-4S for years and didn’t knew the F-4J doesn’t have combat flaps but to be honest most players don’t even know about combat flaps on F-4S since west majority of F-4S players are either low level or bad US mains wo much experience, I’d not consider it as much advantage since 90% of players not good enough to use it as an advantage.
i just use landing/take off flaps. they basically do the same thing
edit: (Some planes got weak flaps!!! and flaps slow you down but increase the lift)
