Any reason not to take Synthesised Stability?

I don’t really get the point of skipping this keystone. It seems like there are no downsides, and it's clearly more profitable to just keep running the same map with a good layout over and over.

Wouldn’t it be more fun if there was some benefit to running a variety of maps? Right now, it feels like everyone will be forced to take this keystone just to stay efficient—unless I’m missing something. Am I?

It costs the # of atlas points to path to and select the keystone.
It's not compatible with collecting maven invitations.
Can't find all the exceptional supports / target variety of div cards by rerunning 1 map.

so there's some downsides along with the benefit.

I dont see it being a good node as a problem.
