Trial of the Gladiator was a ranking system for the Arena coming with Warlords of Draenor. However, it was scrapped and never made it into the game. If you’re looking for some great Arena action, then Trial of the Gladiator is for you. Building on the same system used for the Arena Tournament realm, players who take part in Trial of the Gladiator will be able to enter and purchase gear, enchants, and gems from a vendor, and then match skills with other players.
