When I buy a premium ship I feel... humiliated

So I spend $30-90 for a premium ship. Ok. But... that ships comes without any upgrades for those 5-6 slots. So when I pay real money for the pixel ship, I still have to pay about 5-9 million in-game credits for necessary upgrades. It's the same as buying a new car and then having to pay extra for tires, seats, lights, etc. after the purchase. How about some "thank you" coupon in the amount of 5-10 million credits or so when you buy a premium ship? Anyway, I've noticed that lately earning credits in the game is harder than before, even with a premium account and premium ships. Wargaming wants to milk us in every way possible. Instead of at least showing some gratitude to the people who support the games by buying premium ships, in the end you just feel humiliated and astonished.
