I have crafted a 515 leather bag with extra pockets and a 598 leather bag of extra pockets.
The scaling is not worth the mats used. 515-535 is like just using tier 5 mats, while for a 598ish bag, you are using cooldown mats, but yet the difference is only a paltry 10 lbs?
the extra pockets closer to 600 should give at least 200 more than tier 5 mats, lets be real it should all be scaled up.
Just the cost of the cooldown mats alone on higher gear score bags, is a joke, the mat cost needs to be dropped if the benefits will not be buffed. It is a total joke to require cooldown mats for such paltry gains.
