Tomorrow morning 4.0.1 will drop, and with it several class changes, including the removal of soul shards from warlocks.
With the removal of shards, the soul bags serve no purpose and Blizzard has announced they will be converted to equal value regular bags.
Thus, the Abyssal Bag will become a 22 slot bag.
Abyssal bags are cheap to manufacture, have no cooldown,. and will become glacials in the morning!
Stock your shelves now, resell in the morning, and hello profit.
Yeah, you can admit it. Y'all love me right now.
