In the latest Patch 11.0.5 update on the Public Test Realm (PTR), Blizzard has removed Classic PvP reputation tokens from the Timewalking vendor.
Previously, players could purchase these tokens from Bobadormu, the Timewalking Quartermaster, for 50 Timewarped Badges each.
This change impacts players seeking to boost their reputation with Classic PvP factions. The exact reason for this removal hasn’t been clarified.
The following Classic PvP reputation tokens have been removed on the 11.0.5 PTR:
Commendation of the League of Arathor (Alliance) / 
Commendation of the Defilers (Horde)
Commendation of the Silverwing Sentinels (Alliance) / 
Commendation of the Warsong Outriders (Horde)
Commendation of the Stormpike Guard (Alliance) /
