Material Exchange Feature

I think a new feature that could be added to the game would be a new material exchange. This is a great new system that allows you to exchange your current materials in all rarities to gain other ones but with a cost. This could be added in the 'Global Marketplace' as a new tab. This would not affect the economy of buying/selling materials but rather an alternative to help players get materials. To exchange you have to drag and drop or right click on the material when the 'Material Exchange' tab is open in the 'Global Marketplace', it will then calculate a conversion to other materials which it will display which cost empire points to initiate. To balance it will not be vice-versa. To simplify things a full stack is required for exchanges.

Calculation:

Common Materials - Cost 10 Empire Points per Exchange

1000 Common Material =
Uncommon: 250
Rare: 25
Epic: 2

Uncommon Materials - Cost 25 Empire Points per Exchange

500 Uncommon Materials =
Rare: 50
Epic: 5

Rare Materials - Cost 50 Empire Points per Exchange

250 Rare Materials =
Epic: 10

--------

This would be the maths, as you probably notice it is not vice versa as this could damage the economy.

Notes:

• The exchange accepts and sells all materials except for special event and crete materials
  
• Exchange Rate Percentage modifier is added to balance the economy, this can affect the cost of empire points, this is displayed on the UI of the exchange window, the percentage can be affected by special events - for example -50% (half the cost of empire points for all exchanges) for christmas day
  
• Once exchange is made it cannot be undone
• Exchanged Items can be sold as normal
• This is an automatic vendor exchange and not player controlled marketplace
• This will give Common, Uncommon and Rare Materials more useful and meaning to have
• The economy for common to rare materials will raise from this
• Shops that sell common to uncommon materials still remain
