Missing Competitor's Tabard or Spirit of Competition Pet
The Spirit of Competition was a 2008 World of Warcraft PvP world event.
Players who completed battlegrounds during the event, were rewarded the Competitor's Tabard.
If you have the Competitor's Tabard Achievement, the tabard's apperance should be available for transmog in your wardrobe. If you wish to have the physical tabard, visit Lyesa Steelbrow in Ironforge or Garyl in Orgrimmar and they will sell it to you.
Spirit of Competition pet
If you have the Spirit of Competition Feat of Strenght, the pet should be available in your pet collection. If it's missing, contact us for a restoration.
Note: Customer Support will not grant the pet if you only have the Competitor's Tabard achievement. You must have the Spirit of Competition Feat of Strenght.
