Same cost to upgrade every card?

[mogv]

Just a quick question. In the bazaar you can buy cards from 6-109 electrum so why should upgrading a spark and upgrading a miracle cost the same?

Because, then it all evens out. a card that costs 100 electrum will then have cost a total of 1600 electrum to gain, unless you won it.

I agree with mogv, upgrading cards shouldn't be a flat cost. That said if it was changed to become easier to upgrade cards it wouldn't seem fair to people who put the work in to do it the hard way. That means that the cost of upgrading every possible card would need to remain the same in order to acheive some form of fairness (and even this wouldn't be ideal) meaning that some of the essential upgrade cards may rise well above 1500 in order to compensate for sparks etc.

If the cost was changed at any time the game would become unfair for veterans players
