I actually said that making special pieces for collectors is great. I just think that there should ALSO be some traditional choices for people who want pieces to play the game.
As for market size, they are automatically limiting it by charging three times what a typical miniature runs.
Have blind packs. Have high-grade collector's pieces. But also make it so that if I need a half-dozen water cultists, or a few Trademarked Beasties (TM) that I can get them without having to pay triple or buy thirty low-quality pieces I don't need to get one I do (I've been painting miniatures since the 80s, and still shudder every time I have to try and work with the plastics.)
