The community has been asking for Spell Component Bags for a long time now.
The problem is that the Devs have not been able to get the spell system to properly see the Spell Components if they are in the Bag and use the Component when you cast the spell.
Solution: Add an Equipment slot for each Spell level where you can place your spell components, just like the ammunition slot. Then a Spell Component Bag could be introduced that would funciton just like a quiver, and would refill the Spell Component Equipment Slot, when it reaches Zero.
Thoughts?
