Not sure if it's been thought of b4 but i have come up with an idea and it is perks. U get perks for doing certain things not sure what yet,and some of the perks could be +5% attack,+5% def,+5% deck ect.. and since im not sure yet in how to obtain these perks i would like to see what u guys can come up with. There could also be temporary perks and permanent perks.

Anyone one to add to this idea or atleast give feedback.

that's what special modules (for the ship) are for. Those modules provide good bonuses. Btw, do you or did you ever play any game from the COD series?

Yes i have played WAW,BO,stated playing MW3,BUT i haven't played 1,2,3,or MWF,MWF2.
