I know people being vocal about it mostly don't like.

I personnaly have no problem with it.
Originally, I'm a HW/SB AST lover (for cards). I accepted the new system, it was fun it's own way.

Now, I was also looking for a way to make both defensive and offensive cards work together.

I think this AST version is a good middle ground between what I like about the old and the new system.

What I like the most I think is making Lady finally a good choice and a reliable healing skill to plan in the rotation.

I like the healing boost from arrow coupled with spire shield.
Most of the time, it's good for tanks, but I had situation it was great for DPS.

The 2min burst still stay satisfying to do.
