Please add PvP transmog vendors to BFA in the same way there were PvP transmog vendors in WoD and Legion. There are vendors who sell nothing in the Mugambala, for example, who could be made to sell PvP transmogs for marks of honor.
There are many transmog sets that are currently unobtainable simply because they stopped dropping at the end of their seasons and were never added to pvp transmog vendors like was done with WoD and Legion transmogs at the ends of their seasons. Warfront sets as well, while technically obtainable as far as I can tell, are locked behind dead content that nobody does anymore, and I submit those could likewise be added to transmog vendors near the warfront queueing table.
This really should’ve been done during BFA at the end of each pvp season, but better late than never.
