Blizzard has announced that the Aiding the Accord quests are now available again, and we’ve heard reports from players that there has been a ban wave for players who heavily exploited this bug.
Some hotfixes have been deployed and these quests should be available again.
This weekly quest would previously show up again when relogging and could be completed over and over again, granting reputation and extra high item level gear (Item Level 402) as rewards.
