MerchantI had been thinking about something along these lines. Could be good. I personnally would put the control points on cliff at first, roof on second and balcony at third.
Also might want to add a spire so that everyone will want to play it.
The points would definitely have to be placed elsewhere. The cliff is a perfect first spot, and maybe change around and move some stuff and use the courtyard as second?(obviously some gate routes would have to be changed)
and yea, balcony for third point.
Overall, cool idea and first run of the map is pretty good.
