Card rarity is just stupid by this point.

All card rarity does is just increase the grindfest for all of us. There is no point in having various cards more expensive than other just for the heck of it. Not only that, but most of the time 5000 essence epic cards are worse in a loadout than a 500 common cards. They should just set a single value for all cards, something like 750 essence (average of a common and rare) and legendary cards be 1500 essence, assuming we will still have this shitty essence system.
