Players have found a new way to maximize honor per hour in TBC Anniversary. It's giving them faster rewards per hour for weapons, armor and TBC prep.
But it's EXTREMELY bannable, and you should stay away.
Players (particularly on Alliance with instant queues) are making "lossmades" where they queue up and AFK every game. They get 8 to 10 battleground marks per hour, which is faster than any solo player.
But AFKing battlegrounds on purpose is bannable and has historically resulted in a 30 day ban.
Avoid the "lossmades" and either solo queue AV or join a premade to farm honor fast.
