Was there yet another new, undisclosed update to the game, one that prevents legendary equipment from dropping in the market and that also changes what equipment is available to purchase depending on character level?

When the first round of "major" updates started on July 2nd, the appearance all but ceased for legendary market equipment, but there were still common equipment items in the market. In fact, in the two weeks between the 1st and 3rd "major" update, I only saw ONE legendary equipment appear in the market. Before July 2nd, there was at least one legendary equipment every 2 to 3 days, even if most of them were only for Kobans.

Since the last update on July 21st, all I have seen have been rare and epic equipment after EVERY market update, and still no legendary, and the commons have disappeared completely. This is not just a coincidence and has to be some new feature. I don't mind commons disappearing, but where are the legendary? Is the drop rate so low, they're non existent in the market now?

All that is mentioned in the last patch notes was the fact that market equipment prices were being lowered and would no longer cost Kobans. Nothing else was mentioned about changes to market equipment, appearance rate, or what items would be available.
