Imo second option is quite expensive, tho some1 might want to pay that. Maybe third option in between would be better than lowering higher one?

I think I'd click a button to automatically send 1000 sats a month to the primal devs, with no benefits

Legend has been rolled into Pro (so you get Legend privileges with the Pro license). Our plan is to keep expanding the capabilities of Primal Studio (more on that soon) and therefore the value of the Pro license. We don't have near term plans to revisit the pricing, but I do appreciate your feedback.
