In our attempts to level up our hideouts to make them as awesome as our heroes are, we often find ourselves short on two basic needs...
glue and zeronite.
So with that in mind, I offer this suggestion.
We need a Recycle Room.
SPACE: 1 Slot
The room would take items (capes, suits, shoes etc) and turn them into random amounts of glue/zeronite based on the room level and the level of the item. For example, an epic item would offer the player more glue/zeronite than a regular item. Considering we have the exchange room, we could then go further into exchanging our recycled material into what we really need.
How it would work:
Go into the hero hideout, drag an item over to the recycle room. A tab would pop up saying you will get this much zeronite/glue for this item. You would need to click yes to recycle or click cancel to not recycle. (just like when you sell items for coins). Clicking yes would add glue/zeronite to your storage. If you did not have room for the amount to be recycled, the option would not be allowed.
While the instant benefits of glue/zeronite is obvious, it would also factor into play of "do you want resources or coins". A player would need to balance the two to insure the needs of their hero and the pursuit of rewards.
There could be a recycle Herocon. So many points awarded for items recycled. 1 point for normal, 2 for rare, 3 for epic, 5 for gold. Also, Heroic deeds could implement a recycle option.
