Difficult to say. I don't have a crystal ball, I'm afraid.

My own conclusion that I have arrived at is that this mechanic does not work in this style of mmo, and now they are stuck because they can't just delete it, or AST. I know very little of pre ShB MCH, but that particular job's rework has been well received. AST might be more difficult due to the lore surrounding, and identity tied to those damn cards. I don't think the devs have the same luxury as they did with MCH when it comes to a complete overhaul.

Basically, the job needs Yoshi-P to pull out another rabbit. If it does ever get fixed, it will be entirely different that what we've currently known it to be. That is for certain.
