I've had this idea in mind for a while, and I decided to post it since we're currently re-experiencing the August event :)

People aren't too happy about the current way shops work, so I think it would be better if the shops could be open at the same time. It would still work the exact same way it does now, with the Good and Evil karma bars, only they could both be open, so the amount needed to unlock the shops would be a bit higher.

I think this could also start up some friendly competition on which side, good or evil, could unlock their shops faster.

Let me know what you guys think! I should probably make a mock-up so people can really see what I mean here
