I think it just takes some getting used to. The cards themselves don't seem super rewarding, but I feel Sleeve Draw and Minor Arcana when mastered will show the true power of the new astro.

The Aspected nerfs are what really surprised me. The first dungeon went smoothly with small pulls since it was everyone's first time. On my second run through I had a group of 3 players that were grinding for xp and a tank that pulled huge groups. This is where the Aspected nerfs really stood out. Healing is going to be harder from here on out it seems. No more throwing hots on the tank and playing dps for prolonged durations. You will NEED to use nearly every aspect of your kit in these large pull situations. The same could be said before with new content and possibly under geared tanks, but with your nerfed hots it's all the more difficult.

MP management is using Lucid and Lightspeed (esp. for aspected heals) on cooldown. That's it.
