I like only the casual, cop, and schoolgirl stuff. I can understand why some would be upset, because we should have been had the older DLCs in and it's 89.7% likely your main isn't included in the pack either, which is bound to leave a bad taste in your mouth. :-/
Everything besides the few new ones, should be free. Those are costume packs we bought back in 5U etc.. or that came with the character when you bought them Nyo/Marie/Honoka/Phase/Nao.. what a trash bunch of DLC.. I'll just wait til Ayane's outfit becomes something you can buy separately (because you know it will eventually).
