You may notice that most of the most of the ways of spending Premium Days I listed aren't economy friendly to the premium day spenders. I set it up this way because I rather have it discouraged normal to players from using this from of in-game currency conversion. We all know that most players can earn up to 100K+ Credits in a hour with premium time, really good players will earn up to 500K+ Credits in hour with premium. Witch would make about all of these uses for premium days trade not worth it. Most Whales have over 500+ Days of Premium, I can't even think of the last time I ever needed to buy just Premium Time. All of the times I get Premium Days in a bundle with a tank, and the only reason why I even got it was for the 5x exp multiplier for wins in battles. So these ways of spending Premium Days would give whales a reason to buy just Premium Time, I play for 1-3 hours a day so I feel like spending Premium Days as a currency for credit boosters sounds like a deal to me.

Plus life is full of changes you might not even live to use up all of your own premium time in game.
