I think they won't, drop rates are the same like they were in the past, for a short time after aniversary K stone also dropped at Morhaven D, Rooftops, which was a bug. Besides K stone dropping in a place which was not intended, also the overall drop rates (form barrles, breakables etc) were higher.
after update they fixed it.
Think now it is as it was supposed to b.
I do agree wth u, was more fun when drop rates were higher.
