World Drop Farms Dropping Zero items after 1 Minute *BUG?*

I applaud Blizzard IF this change was implemented to discourage botters. I am a avid farmer and have been doing it long enough to remember when once a node was picked it disappeared for a bit. Botters made farming a bit more of a challenge then and were driven by greed vs game immersion and enjoyment. Also remember that Blizzard, at that time, was great about addressing/disabling bot’s when reported. My issue with this change is getting nothing…0 drops. This seems to interferes with game immersion and enjoyment. Seems with all the talent that Blizzard employees someone could have come up with a better way to combat bots without impacting actual players quality of play.
Just a thought…
