Yes, you do earn Frostwolf Clan/Stormpike Expedition Reputation. (best chance you'll get at getting conqueror title.) You get 10 timewarped badges per AV win. You need to collect total of 200 timewarped from AV to get the special mount. (looks like you might need to submit ticket to a GM for this mount if it doesnt get automatically added to your collection tab) Yes, these timewarped badges can be used to purchase epic gear from the AV vendor. AND YES. The gear the vendor sells scales. (im personally going to first purchase the mace to have an easier time in AV ) Heres the rewards you get from the main special event quest. Looks like you can purchase the one you dont choose later on from the vendor It seems you need BFA in order to queue for PvP event.
