My banks slots are so full of tradeskill and quest items, that on several of my toons, these items are spilling over into my character inventory slots. With the number of expansions to tradeskills and quests, the bank has not kept pace with the multitude of new items needed to practice these skills. Granted, with the addition of the Keeper of Lost Things, its no longer as necessary to hold extra equipment in the bank in case you lose your character, and all his gear goes permanently "poof!" But still, we need more space for all of the other stuff. I remember when spell research was basically combining two items in a book. Now its two or more pages, and a couple of other components. And you better have multiple stacks of each because of how many combines it takes to get your skill up a single point. We need more inventory space to keep all these components.
