Basically we removed cosmetic gear exceptions to simplify the code when looking at new challengers’ gear. Old challengers will be grandfathered in under
the old rules. The new rules take effect January 1 2018 at Midnight PST.
All characters are no longer allowed to use green shirts / tabards except for Worgen Hunters, Rogues, Warriors and Blood Thirsty and Green challengers.
Those specific Race-Class combinations have the green shirt automatically equipped on character creation. It is important to know that you CANNOT unequip that shirt to put something
else in the slot or else you will get flagged.
