Hello, I spent $100 to get spins to gain the new skilling outfits. I have always got (all) the full sets from the other promotions without fail for $20 to $45. There has been some kind of bug I believe. I personally don't think it was just "bad luck". In total, ~490 spins for 19 of the 20 needed for the set. This is just not cool.
Also, seeing as most skilling outfits only consist of a few pieces, it would be understandable for this outfit to cost more. If you need 4 or 5 times as many pieces for an outfit it makes sense for it to cost more than other promotions.
