After further discussion, we decided not to remove the rusted and ironbound proto-drake rewards for the normal and heroic Glory of the Ulduar Raider meta achievements when patch 3.2, Call of the Crusade, launches, and currently have no plans to remove them in the foreseeable future. However, we will continue to evaluate the situation and if a decision is made to remove these rewards at any point in the future, we'll provide a one month warning so players will have time to make some final attempts.
