My issue with the whole rework in 5.0 is that the card system they implemented is nothing more than a illusion of choice. There is no difference in the current card system to for example a buff ability such as divination other than the enforced role RNG.

The reason many of us loved AST was because we had different buffs we could supply the party with: We had defense, attack, haste, refresh, crit +, regain. Sure balance fishing was a bit hard to discourage, but they simply could have buffed the other cards to make them more on par with balance, or if necessary nerf the balance card.
