In the challenge campaign store, the value of the AD packs (unbound) exceeds the value of Enchanting Stone 5(bound) and Companion Token(bound)
Here is the AD value per Heroes Medallion spent:
2,777 - Upgrade token (only if used on a Legendary upgrade - the others are less efficient)
2,300 - Enchanting Stone 5
3,333 - 50K Astral diamond pack
4,266 - Mark of Potency 5
4,300 - Mark of potency 6
4,160 - Mark of potency 7
4,280 - Enchanting Stone 6
This is a major problem for incentive. It is cheaper to upgrade companions using the AD pack, its a non-reward.
SUGGESTION: make AD the worst exchange value (by a little) since it is the most flexible.
Reduce the cost of Companion Upgrade Token from 3 Heroes Medallions, to 2 Heroes Medallions.
Reduce the cost of Enchanting Stone 5 from 10 Heroes Medallions - to 5 Heroes Medallions.
THIS CREATES THE FOLLOWING VALUES:
3,333 - 50K Astral diamond pack
4,166 - Upgrade token (only if used on a Legendary upgrade - the others are less efficient)
4,600 - Enchanting Stone 5
4,266 - Mark of Potency 5
4,300 - Mark of potency 6
4,160 - Mark of potency 7
4,280 - Enchanting Stone 6
