A lot of people are under the impression that nexon has a hand in this and the only data they are collecting is how much gems they sell with the loot tables the way they are. Why an Anet dev doesn't respond at all is on a lot of people's minds.
I am slacking at work and might have missed some of the facts. However, as this "bug" is steadily approaching a month old many are fearful of the direction gw2 is taking.
Here's hoping it is a bug and gets fixed soon.
Also the mystic forge appears to have a decreased crit rate as well.
