So, now that a few seem to like the idea of talking about upgrade prices, how do we suggest we build the scale for prices? And how would this work for low cost cards if upgading was a time base cost thing, because pilliars and photons, ect, would be way to cheap to upgrade. Maybe make a lower base price, with times card base cost added?
Or, we can just earn 1500 from every win and lose, effictivly stoping grinding forever. How much fun that would be.
Or a diffent wheel we pay ~700 to use, and it may upgrade a radom card in your deck.
Note: Number two is not an actual solution, please feel free to refrain to refer to it seriously in your next post. Like I did, : )
