I've been "grinding" Copied Factory once per day since 5.3 dropped since now is the time my twisted mind decided it has to get this minion (figured more people running it because of upgrade item means faster queues). Haven't seen the damn 316 drop even once. I ran the raid about 20 times or so back when there was a weekly drop and only ever saw the 316 maybe 4-5 times? It's bad man real bad..
