With the patch and battlegrounds now live, we wanted to take a moment to look at the Warsong Gulch vendors. They worked in original WoW and now work in WoW Classic like this:
Warsong Gulch vendor lists only appear when you have the required reputation. You should see the text “What items have I earned the right to purchase?” and, when you’re Neutral with your WSG faction, you should find that you don’t have the right to purchase anything.
Warsong Gulch vendors will only sell items from their original list of consumables (and one tabard) for now.
Additional items that were added to original WoW in patch 1.6 will become available when Blackwing Lair opens in 2020.
