They broke the central system that made Astrologian fun to play, so they should just go all the way. Remove the card system, give us 6 healing abilities and a button to buff raid dps by 5% every 120s. They'll never make the dps buff worthwile outside of very coordinated raid groups, because if it's worth it in PUGs it would break the raid content for high end raid groups- That means it's not worth to invest all the busybody button clicking and avoiding GCD clipping as a playstyle either, where you are also shafted by having less heal abilities with worse CDs and potencies.
