If our remit on 'what do we want to see' is solely focused on AST itself, I think EW healer is the basis that should be built around; it's the one time we should be keeping AST as-is. The cards work well for their purpose, the influence of RNG is as mitigated as it can get while still being there, and removing it while still keeping AST's fundamental identity requires a retooling that's likely to do more harm than good. It has problems, but so does every other job, it's all about picking the cons you're okay with having. I don't play Ninja, but that's not a failing of Ninja, it's just not to my tastes. Really, the failings of AST in my mind aren't AST's fault at all, it's that they're a healer in a game that doesn't really know what to do with healers.
If I were to answer 'what do I want to see' as an AST player, none of my wishes are about AST. Instead, I just want tank self-sustain to be kneecapped. The angle of 'if there's an imbalance in a role, buff everyone to be on the same level as the top' has gone on so long for tanks, mostly in response to Warrior's sheer unkillability, that it's no longer a problem you can fix with any change to one job; you need to nerf everyone.
