They really have a few avenues they could go down with the cards
1) revert to a slower version of ShB AST where all cards are DPS but it’s RNG which card you get and each card biases a particular role so you have to consider if you want to give a card to that role or redraw it for a different role
2) keep a similar system to now but cut out non card heals that do equivalent things, like if you want spire to be a shield you need to reduce how much we use CI
3) make cards non healing and non damage- ie pure utility
Right now the current card system suffers from being a watered down ShB system shoved full of pointless heal bloat that just mimics the healing we already have too many charges of
