Does this have to be an AoS? It sounds like such an epic idea, I don't think you should add it to the list of 5000 AoS maps.
what else would it be? another RPG to add to the list of 10000 RPG maps?
a tower defense? that wouldnt make any sense at all.
a hero arena? Another hero arena to add to the list of 20000 hero arena maps?
