I mean, the basis of almost every competitive closed map is a three lane idea.
Mountain Fortress: Left (alley), mid (tavern), right (fisher).
Fort of Honour: Left (bridge), mid (apple), and right (ruins).
Sandi'boush: Left (grave), mid (mid), and right (alley or just right).
Naval Outpost: Left (enemy spawn), mid (catapult), right (shrine).
Etc. The only maps that arguably break this idea are Verloren (4 lanes) and Nord Town (kind of an awkward layout if you think about it). It's less of a problem of what maps were chosen, and more of a problem for the state of competitive.
