Which opens the door to another exploit, since you can keep asking the tabard vendor in your city for the lost Blood Knight tabard every time you log back in, guild tabards will keep stacking up in your inventory as you log in and out to repeat this, and you can sell those for 25s at the nearest vendor. Doesn't seem like much, but still has a potential for a large amount of gold/hour.
1. Visit tabard vendor, and select option "I have lost my Blood Knight tabard and would like to reclaim it",
2. Log out and then back in and check that the tabard in your inventory is now a guild tabard and sell it to the nearby vendor,
3. Repeat
4. Profit
