Forager Bag stats

[Phelonious]

A few of my RL friends and I had this bag pre-nerf. We all did the math and it was obvious the bag was reducing the weight of whatever you put in it by 250%. We checked and rechecked using various heavy objects like bricks of ore etc. If you placed enough weight in the bag, your total weight would lessen... by 250% of whatever was in the bag. The bag's pre-nerf description said it was supposed to reduce the weight of the contents by 25% and it was changed to 50% and allowed larger items iirc when they nerfed it. Also, if this was a "classic bug" in general, why was the Forager's Bag the only weight-reduction bag affected? It sure seems like this was an error limited to the Forager's Bag.

edit: Back then I regularly duo-ed with a monk (I played a shaman at the time) who used it to great advantage. She was constantly being told she was way over her weight limit, but she just played stupid and kept tanking away.
