Yes I am aware of the various ways of increasing storage, I was concerned about "immediate" storage. Over "there" one can craft items no matter where the mats were stored, here they have to be in you immediate inventory. Yes I know what Key items are, the point was that there are a very, very limited number of such (at least that I have)... so why waste so many bag slots?
Seems a design flaw to me, I was just trying to see if there was any "excuse" for it or why it can't be changed.
