I thought people were concerned about the increase to the price of a glamour set, not the full price of the set. If the sub fee increased $1/mo but the price increase is $4, that's only 4 months.
The next question would be when was the previous time a price increase was implemented on comparable sets - and what would even be a comparable set in the first place. Was this set originally released in China or Korea like most of the non-cosplay sets, or is it a rare occasion of a set getting an initial release to JP/NA/EU?
Doesn't change that if you don't like the price, you have the option to not buy the product. You don't need it to play any part of the game.
