The direction of this expansionly rework is enigmatic. I'm not sure who it is for, or who it is targeting. There are clear problems and contradictions.

Cards

They wanted to add utility back to the card system, so they removed RNG. Cool. I can get down with that. However, most of the utility they added back in is half-baked. The Ewer looks insanely strong, but the other 3 seem quite weak. The Bole is Exaltation but available half as often and involving a second step, The Spire is Celestial Intersection but available half as often and involving a second step, and The Arrow is either buffing your SCH's Spreadlo during ~1min window every 2m or probably getting overwritten.

APM is cool, but everything needs to feel like it does something. That's been a hallmark of every iteration of AST so far, and this is the first expansion this feels like buttons that will accomplish hardly anything -even in a prog setting- (I see you tanks and your sick personal cooldown and healing buffs). With no interplay or reward for using cards that probably will feel like they accomplish nothing, I'm not sure how much people at any skill level will enjoy.

The Oversights

Macrocosmos now being a DPS loss (it is still 250) sort of suggests an oversight.

The MP economy is currently awful, to the point there is no way this build ships with it. It is the same model as SCH, but 15% less every minute. At a current 2.43 (the slowest BiS possible), we run out of MP in 6:33. That again, suggests a complete oversight, and they just didn't adjust current Draw's numbers. If this is intentional, I'm not sure people who wanted to get into AST but "it was too hard" are going to enjoy never having mana to cast spells.

Our One New Button

Sun Sign makes very little sense. It's good, and will be strong, but being so closely coupled to a button that already handles all of the mitigation in a mechanic by itself usually, and only getting to delay it 10s past the end of that button is pretty weird. I'm not sure why they didn't give it the Earthly Star treatment and make it last 60s, upgrading after 30 or 45 or something, other than they just didn't think about it.

Other than MP, I don't think anything else warrants excessive complaining about just yet, since I don't think we have any great solutions until we get to play with it. I'm just really not sure who this rework was targeting.
