function for dupe covers that works for players and devs

rossmon

They ought to create a "white" cover. If you get a cover you don't need, pay 10% of the cost to buy said cover, in order to change it to a white cover. This could be applied to any cover of the same character. so 250hp for a 4* or 79 command points for a 5*.

Then, a higher percentage for character exchanges. maybe 30% for a gold cover that can be used on any character of it's class, 750hp or 217 command points. but probably preface this with you have to have either 5 covers in that color, or 13 in the character.

So if you get that 6/7/8th black hulkbuster, you can trade it (and 250hp) instead of 2500 hp to buy a white hulkbuster cover that can be used for any hulkbuster.
or if you get that 14/15/16th Invisible woman cover, you can trade it (and 750 hp) to buy a gold 4* cover that can apply to any other 4*.

Since 5*s require command points instead of hero points, I applied the same ratio.

This is a functionality that would make players happy, and lessen the frustration with the RNG, and still provide a flow of income to the developers.
