A nice feature coming in patch 9.1.5 is the new Scouting Maps, which will grant (most) flight paths for each expansion including Shadowlands.
Because these items are toys, they only require a one-time purchase and then can be used on every character, even those created in the future.
Previously, there were maps for the original World of Warcraft zones Kalimdor and the Eastern Kingdoms, but now there is the option to have access to all expansions.
The only issue is they will set players back a hefty fee, as there are 8 new maps, which each cost 10,000 gold each. The good thing is players can pick and choose which maps they see are necessary for what they need them for.
New Scouting Map Toys Coming In Patch 9.1.5 Grant Flight Points For All Expansions
Another deterring factor is that players will need each explorer's achievement from each expansion on one character before they are able to purchase that expansion's respective map.
These new maps do not teach every single flight point, as some are locked behind unique factions or questlines, but the majority of what players need to get around will be available on purchase.
These maps can only be purchased from each faction's Heirloom Vendor, with Krom Stoutarm in Ironforge for Alliance players and Estelle Gendry in old Undercity or Orgrimmar after the destruction of Lordaeron for Horde players.
