They recognize that the items are high-end. They've always said they don't want them to be easy to get. However, they simply don't want the same people getting them over and over. It's hard enough with only people who have never gotten one there. Professional hunters need to move up to things no one can solo and leave these things to people who need the items.
My guess is that leaping boots aren't going to be easy to get. They're high-end. It's not going to be poor little LL standing there waiting to be killed in a BC20.
Where will gilsellers go? Eh, they weren't at LL, VE, or argus on our server for the most part. They'll go where they already are--JP crafters and serket parties.
