They basically nerfed the best card ,while leaving the majority of the other cards borderline useless.
You don't have more choice, balance will remain the best card in most situations.
If anything this just makes AST less strong, possibly less desired.

Besides how can people even argue when ever a healing class is too strong or not, even more so why do they care?
The game doesn't even officially support a parser.
In fact this community has been so much against parser that I honestly don't understand the complaints about balance.

As for the devs, well it doesn't take rocket science to understand that the old balance was overpowered.
Though if you nerf what is strong, than buff what is weak.
