Ways you can really walk: round slopes, water, cliffs and enemy towns, by flight, ship, zeppelin and tram. Gather plans its routes with it; /bv route leads you anywhere.
Find anything in Azeroth: NPCs, trainers, flight masters, zeppelins, instances, mailboxes. Put several places in a tour and BV Routing leads you through it the shortest way.
Herbs, ore, fishing pools and treasure on your maps, a route editor that knows the terrain, a gather mode with HUD and a session tracker with gold per hour.
NPCs, trainers, vendors, dungeon entrances, mailboxes and meeting stones for the BV Addon Suite: Routing leads you to them by name (from the vMaNGOS world database, GPL-2.0).
