You do not want 1 demi-summon every 2 minutes no matter how much variety there is, nor have it be dependent on building up stacks of Aetherflow and Trance. Even a single death was a large setback when we had this system. I agree that Aetherflow is a bit floaty at the moment with it just kind of mostly existing on its own, but it absolutely should not go back to what it was before.
