I understand that a Hero’s “Specialization” is something modular that varies from Hero to hero, whereas the Mastery Cache is a common element. But there’s no need to let that fact about the design dictate where this information is presented in the player’s “UI” so to speak. In the image below, the 2 pieces of information I’ve highlighted are functionally linked to understanding how Memory and Mastery work with Vixen, but they are scattered around the card. I would prefer them both displayed along an edge of the card that’s dedicated to Memory/Mastery (and I personally prefer the bottom edge).
