You say that because you have several hundreds on your bank.
Irrelevant, no one in their right mind would use that feature. So the point is not valid at all.
They are important for players who need to buy something. In your case, you have if not everything almost everything, that’s why credits are worthless for you, and that’s why you can afford throwing a hundred million of them for monocrystals. But again, that doesn’t mean it’s a fair trade.
GS in the other hand are the right money to pay for monocrystals since it’s the money that prevents you for grinding.
Again, if you’re not willing to pay real money for them, just do the daily grind and you will get them eventually.
How much time will I have to grind to get 8400 monocrystals to be able to build all top secret projects?
So far I got over 840. Enough for 2 ships.
I will do simple math here. Correct me, if I am wrong.
How much time will I have to “grind” to be able to obtain just the ships, not any mark V’s.
Materials are not the problem. I can get them.
10 ships, each type and role. Jericho will have one more, Torpedo Frigate. Rank 14 ship will be probably moved to rank 15.
I day = 9 monocrystals (premium license)
10 days=90 monocrystals (premium license)
100 days = 900 monocrystals (premium license)
So, I would have to constanly play free daily missions for over 3 months of time to get 2 prototype ships (premium license).
almost 14 months to get all 10 ships with a free option. Well, it’s free, so I can’t really complain, I will just have to play it more. 
Of course, I could also spend money and maybe I will, but not before the new year.
Still, crew option is still payable. I want to get maximum efficiency, so I guess I’ll buy those slots as well.
Tell me, is every slot 2000GS or it gets higher?
Thanks, Resi.
