as with most maps often the knowledge of the mapmaker is key to what actually ends up on a map, something to remember is nothing ingame is done from a gods eye perspective, that particular map may have been chosen by fran because it had the feature on it she needed, and didnt care whether the ridorana was on it or not

what im more curious about is when we get the final updated world map for 5.0 (the one we as players will actually use) will those details be included in the map, and are details being intentionally omitted from that map by devs to prevent potential spoilers later

also super SUPER happy valnain is on that map for reasons
