i'll let u in on a bit of a public secret.
when the game was first launched, medal drop rates were high, everyone would play for free and be prinzessin, get huge armies, get bored and quit. this meant the game didnt really make much money since there are no advertisements (like google ads) on the game page.

so on newer servers they slashed the medal drop rates so people are "forced" to buy medal boxes or, farm endlessly. there are people who buy their way to prinzessin, and some who still farm the old way, but it takes way too long. also it involves a bit of luck.

u may not like how it is, but it does make business sense, the game needs money to stay afloat you know.
