The default or starter loadout cards on each merc is stated as ‘EPIC’ rarity, which seems to be untrue. Id imagine they should be labeled as ‘COMMON’ or simply as ‘DEFAULT’.
The outlining of the cards are also of ‘COMMON’ rarity color instead of the violet hue of the ‘EPIC’ quality.
Not sure if this is actually a bug or intentional, though it would be appreciated to either change the label or the color to better differentiate between your loadouts.
