the main issue here is not the shisui set being worth of dyes, but them being handed like that in an event that is known to give unique stuff every year when the dyeable shisui could have been crafted gear.

I, for one, was really expecting an actual hingashi kimono for this event, because the 2 vanity armors we've been getting lately is the Taoist and Ao-Dai set, both resembling chinese things, not japanese kimonos at all.
