Knowing blizzard its going to take them a month or longer to add them and be usable by anyone regardless of title/rbg. Since they are just going to use the actual gear instead of the replica gear, it would make no sense. Just add the replica gear is they still want the rank/title requirement.
It was cata, however, they stated they are not going that route this time around. There will be NO replica gear.
PvP Item Transmogs
Rather than utilize the Replica PvP Vendors that were originally added in patch 4.3.0, we’re changing all of the original WoW Classic (Era) PvP gear to be usable as transmog appearances.
All of these pieces of armor have been and will continue to be available from the Legacy Armor and Legacy Weapon Quartermasters in both the Champion’s Hall in Stormwind and the Hall of Legends in Orgrimmar.
