the purpose of buying skins is to indirectly support ED´s development. I´ve always taken this in consideration when buying skins
Sorry but it's not, the purpose is to get a cosmetic skin.
People have paid for the game and they've paid for expansions.
Sure buy them to support if you want, but that is not the
purpose of them. Saying that's the purpose is exactly how you end up with $400 Star Citizen ships being "normal".
I buy a skin because I want new cool skin, easy. This line of thinking keeps prices fair and discourages shoddy skins being produced. If it turns out to be rubbish (a few have been faulty so far) then you just ask for a refund.
