Actualy, a rank 3 skill only aply in rank 3 ships or highter. Instead this, put this way by exemple:
-A t2 skill only aply in t2 ships or highter
T1- rank 1,2,3: Any ship t1 will have all skill i learn in t1.
I say this because i want use the black boomber(t3 rank 8 fed interceptor) as my main t3 ship beacause this ship is faster. But i want the rank 9 skill on this ship(increase afterburn speed in 20%).
I sure this change no going mess the game balance.
Sry my bad English
