At least on the Guards that remain in the towns they have taken over. On Pacific, both Moonglow and Cove have lost to the Bane, and the guards remain there. I thought great, I can go get a few more Defilers of Virtue, but no. Today, I went to Moonglow for about an hour or two, solo and killed Bane guards, nothing. Tonight I went to Cove for about two hours and killed Bane guards solo, not one dropped. To give you and idea of how many I killed, I banked about 400K from killing them and they have 4k to 4.5k each, so just shy of 100 and not one Katana. Again, I know the RNG sucks, but that is ridiculous. Three days ago I was killing them at Moonglow and about every 10th one, or so would drop a Katana.
