There's no point in the Rare Gem being a container or crafting reagent, whatever it is. Why not just let the Chest + Key bundle drop from chests? Seems alot simpler. Having an item I have to click and watch a lenghty animation for just to have to click ANOTHER button and watch ANOTHER lengthy animation to use the bonus chest is a bit redundant and cumbersome.
