I don't know how many rounds of WoB Drop will do, but I say keep 'em coming. The ability to score them at a pre-order/GB price AND use a DKC is incredible.
Classic colors, and great price for GMK. After DKC rewards & sales what a great price.
Kitting could probably use a few minor modernized updates (4-key 40s, full HHKB support), but no real complaints.
