Hi!
A group of friends and I decided to look for a “dead” server one with 0 Heroic Lich King and 0 Anub’arak logs. After a bit of searching, we found that the Myzrael server had no recorded H LK/H Anub kills. We decided to take this risk because two other groups had gone to the Angerforge and Maladath servers and successfully managed to get a couple of Realm First achievements.
For instance, on Angerforge, ‘Death’s Demise,’ ‘Celestial Defender,’ ‘Grand Crusader,’ and ‘Realm First: LK’ were available. Out of these four ‘Realm Firsts,’ they only got three; the one they didn’t get was ‘Grand Crusader.’ A similar situation happened with the Maladath group: ‘Celestial Defender,’ ‘Grand Crusader,’ and ‘Realm First: LK’ were available, and again, they only received two out of those three achievements. The achievement they didn’t get was also ‘Grand Crusader.’
So, tonight, our group successfully got ‘Realm First: LK’ on Myzrael but did not receive ‘Grand Crusader.’ On all three of these servers, no one managed to defeat Heroic Anub’arak because the fight was too difficult at the time, and these servers had a low population to sustain a highly competitive raiding scene.
After not receiving 'Realm First: Grand crusader or Heroic Anubarak on Myzrael, this led us to the conclusion that the ‘Grand Crusader’ achievement itself is bugged. I would assume the developers forgot to adjust this, especially since even in original Cataclysm, they had to modify it to make the achievement still obtainable without the limited attempt system. The reason they changed it when Cataclysm came out was that ‘Grand Crusader’ still hadn’t been claimed on a significant number of servers, so they gave people the chance to get it in Cataclysm.
I was initially going to post some evidence, but the forums don’t allow links. However, there’s another forum post where a user provided a Reddit post and wowhead comments, both from 2011, that prove this achievement was still obtainable during Cataclysm
I’m also going to post the raid lockouts (IDs) in here. Please take a look into this, as we don’t know when these servers are getting shut down, and it would be a shame to see this amazing title go away unclaimed because of a bug
