Early arrival of BlizzCon pets for Virtual Ticket holders?? eeeeeee!!! pic.twitter.com/vJMaYBMqxD— Quintessence (@perksnpeeves) November 2, 2016
Select each entry and click on the gift icon in the main window. This will "open" your redeemable pets and ta-da! Two new pets! :D
Although we'll receive both pets, each one can only be summoned and used in a Pet Battle by the appropriate faction. Legionnaire for Horde and Knight-Captain for Alliance. Gotta represent your faction, I guess!
Oddly enough, when each pet is summoned they spawn in as level 110. This is likely a bug...or they've somehow hacked the game and boosted beyond level 25. :P
