"Into the Fold," the start of the Wrathgate questline

Arguably one of the best questlines in the game, the Wrathgate questline was my favorite in WotLK and remains to this day. Unfortunately, the initial quest, "Into the Fold," cannot be picked up from the quest giver. I am level 72, obviously Horde, and want to know if there is any way around this bug. I have already seen the bugtracker report initiated by another player and upvoted it (link here: https://www.warmane.com/bugtracker/report/17900 ). Unfortunately, the bug seems to have gotten little attention in spite of its initiation being at least 3 months ago. However, this leads me to believe there may be a way around it, so I am asking here to see if there is.

Again, I am level 72 and Horde, and I have done the prerequisites according to the guide posted on Wowhead's comment section back in WotLK. I will gladly do any other quest I need to do or level up more if that's what it takes to do this questline. I am inclined to believe I am missing something due to the low response to the bug report, but it could just be that not so many people level exclusively through quests like I do, or there are still too many people who haven't reached this point, or any number of other reasons.

Please, if anyone has any information on how to get this questline started, I would greatly appreciate it. Thank you.
