Why don't astro cards stack?

[HyoMinPark]

this is a very bad way to rebalance. they should stack differently then or refresh durations or be queue'd so that they're not overriden. if i happen to be playing AST with another AST that doesn't know this, and i AOE balance, and he AOE's something else and removes my balance off everyone, the whole group suffers because of poor design choices that should not be the case. there are different ways to rebalance a class without making half their benefit becoming limited by simply being grouped with a second player of your same class.

Then educate them if they overwrite and you think they may be unaware of it being an issue. That’s also not hard to do.

The issue with your suggestion of rebalancing the cards to allow for double stacking would mean that one would have to nerf their potencies. A nerf like this would have to be handled very carefully, otherwise you risk breaking AST in the opposite direction—i.e., making it worthless and not wanted (this was the case when AST was first released in 3.0, and it suffered from that stigma for a while even after it was buffed to be made better).

As it stands now, there is no reason to break the job in the opposite direction just to deal with a mild annoyance (card overwriting) that can be rectified by educating and communication.

it's not difficult but it will happen with randoms until it is changed no matter what level of communication you preach. it's bad design and they should rebalance them in such a way that you can't screw each other over.

Unwillingness to communication and cooperate =/= bad design.

"buff stacking is OP? well then let's not let it happen in the first place! simple

This has already been taken care of—AST cards don’t stack, nor do they need to.

This is not something new. There are other party buffs in this game that do not stack. Refresh and Tactician buffs do not stack if you have multiple physical ranged. Nor should they. DRG’s Battle Litany do not stack. SCH’s Chain Stratagem do not stack. WAR’s Shake it Off and PLD’s Divine Veil do not stack. This is not “lazy design” — this is preventing players from forming meta comps with double jobs and ousting even more roles from optimized settings.

Ironically, regens do stack, all of them.
WHM and AST, two WHMs, or two ASTs, you can stack all their regens.

Two ASTs cannot stack their regens or their shields.

WHM + WHM = stack
WHM + AST = stack
Di AST + Di AST = no stack
