Statistically, on average, I kill each one of you… nvm…
Statistically, we get a cobalt for every 247 Crates and 212k Credits for possible trades. Either dropped or crafted by all materials from the crates.
So with this value in mind, Id personally think its would be fair to recraft a single card at the cost of 50k ~25%. 1:1 ratio.
Further options:
Only change the loadout of the card to a desired one for 300k. Thats 150%. Hefty price tag but worth it.
For another 100k you could switch the camo.
and i believe we can find a hefty cash value (50$?) too that would bring a good amount of cash to the budget. The current gamble mechanic really turns me off and I refuse to spend money on the game so far even though Id like to support the developers for their great game.
