you already have the option to " Dismantle "   unwanted / surplus to requirement / old Equipment 

although now that the game has the daily / weekly / monthly Quests & " Savings points " are easy to acquire for FREE 

And obtaining additional Hero profiles is so much easier  ...   

why would you want to throw the equipment away ??

 its Worth keeping ALL your old Equipment of Legendary quality  

as most of it will be used as a component for either Arsenal equipment or inquisitor equipment 

the only reason i can see for wanting the option of " Reclaiming ALL the materials " .... 

would be to benefit those who Rolled the dice on low % chance of making Legendary equipment ....  and created only Epic or Rare ...

which then allows a player to repeatedly take a low chance on making Legendary  ...  and then "reclaim" the materials when they fail

p.s 

if the problem is your inventory is FULL 

please check your ... ITEMS /  My Items / Bonuses ...   @ the very bottom of the list is the item " Inventory Expander "

each one adds FOUR slots to your inventory 

Just to clarify. If you select an item from your Stock there will be a Dismantle button. If you click it, you get a message saying any gems or runes will be destroyed unless you remove them. It also says you will get 1 item that was used in its construction. Then there is another button to proceed with the dismantling.

@ Strider Is your suggestion that all of the materials be recovered with the aid of some kind of tool that the players would need to buy?

You can make suggestions here or through the Ask a question section in the Menu. The moderators here read the messages but don't always respond. You always get a response through the Menu but it will most likely be a form response.

IIRC, @RogerMontgomery has said all suggestions in this forum topic (channel) do get forwarded for consideration.

A suggestion, being what it is, usually needs no response (given that). (IMO.)

[i.e. No fault to anyone if no followup / response.]
