Just a heads-up to fellow achievement-hunters that Glorious!, the achievement to kill all rares in Pandaria, doesn't share account-wide progress like Frostbitten and Bloody Rare do. You have to kill all Pandaria rares on a single character.
All achievements are like that, according to how blizzard stated it. You cannot share parts of Achievements to other characters unless the "Part" is an achievement within itself like the ones for Meta Mounts.
Hence the "possible bug" in the thread title. I'm letting others know, in case they're like me and didn't specifically look for the blue and were hopeful Blizzard would follow their own precedent (I know, how silly of me).
There is no need to explain how achievements or account-wide achievements work, folks. I am not ignorant of these mechanics.
It's not highlighted blue, so I'd think it's intended.
At the current re-spawn rate it is by far the easiest kill rare achievement. Was able to complete it within the first week. So shared or not I don't think it will be a big deal.
Loser since Feb. 05'
Didnt know the pandaria rare achievement wasnt account wide.
