Why don't astro cards stack?

[Killersai]

Because that would be absolutely broken if you could do things like stack two balances on an entire party.

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.
