Here's one I think should be pretty easy to understand. Add a tab in the storage vault just for collector items (the drops that collectors trade for) from the campaigns/expansion similar to the materials tab.
Collector items take up an ungodly amount of space if you...collect them.
Just an idea.
EDIT: I wanted to clarify, the collectors items I meant are like Skale Fins, Mummy Wrappings, Skelk Claws, stuff like that. The little stackable items that collectors in-game will trade for. These add up and you never know how far down the line we're going to use them. They sure do throw a lot of collector mats in the game..
