With the first Dragonflight Alpha build, it has been noted that a fifth bag slot has been added! We have initially attempted to test what bags to fit on this fifth bag slot, but no normal bags would enter that slot.
The answer for this mysterious bag slot was revealed in the Group Media Interview with Ion Hazzikostas this Wednesday. According to Ion Hazzikostas, this fifth bag slot is actually going to be a universal profession bag!
