Ehhh, I dunno about "stacking" effects, but it would be nice if one AST's expanded card effect didn't overwrite another AST's preexisting extended or enhanced single-target effect, since those potencies are stronger. Somewhat minor, but there have been times when a co-AST single card buffs a party member (say, arrow on a BLM) and I have an expanded balance ticking. I think a card's relative strength should take priority between 2 ASTs, ie: Expanded < Normal/Extended < Enhanced. A normal/extended card wouldn't overwrite an enhanced card and an expanded effect can only overwrite another expanded effect.

Is this really an actual thing? Because there have been countless 24-man raids where I see one double healer party (or more) and looking at the other parties figure the algorithm should have just made a party with an AST/WHM each instead of AST/AST and WHM/WHM parties. Or AST/WHM and AST/SCH instead of AST/AST and WHM/SCH. Unless 24-man raids are the exception to this rule.
