I disagree, mostly. I want to see more character costumes released, even the ones like this that are 90% available in the game. The model exists and the work has already been done to adapt the model for other races, so why not give players access to it if they want it?
I want them to put more of these up, not necessarily expecting people to buy them, but still making them available for those that are after that very specific piece or want it to be non-class-locked. I don't care about cash shop stuff being "high effort" or "low effort", so long as it is priced high or low accordingly.
That said, I agree with you on this one being overpriced. It (and the other things I'm wishing for) should be at the same price point as the ARR Scion sets. Still, they have put it at the newer standard NPC price point and the marketing team is probably not up on the intricacies of why the oldest sets are priced differently.
On the subject of players who don't realise you can recreate something like it in-game... how much of the population is that? It just seems natural to me to look around every part of the game for what glamours I can get, and these are not exactly obscure. The gloves and boots come from multiple sources at level 15 and are one of the first really nice in-game glamours you get access to, and the coat can be found on the marketboard. I immediately recognised that Ysayle was wearing reused player gear, just like every other character at that phase in the life of the game.
Do people really have that little awareness of common glamour items while also caring about glamour enough to pay for it? Honest question; it's just outside of how I've always approached the game.
(And is this why people keep repeating "healers get nothing but white robes" and "there's no good dancer gear"?)
Edit: not a direct dig at the post above which appeared while I was writing this.
