Wait until your FC is 50 and stop rushing it. The more you rush it the older the game will get and it'll get Insanely boring.

I've come to a point where I don't want to progress any farther then I have until later.
Everything will be cheaper and more things will be fixed most likely.

(Repairs, etc)

Go play a new class, go level and help your FC, play with them.

Game came out two weeks ago, no need to rush.
