I came back to retail after a big break from the game since MoP. I’ve read about the achievement " Breaker of the Black Harvest" which you were awarded for completing the green fire warlock quest back in MoP days. My warlock with the fel flames doesn’t have any achievement nor title awarded. I’ve read in wowhead comments that you had to have an active subscription during the WoD release to be awarded with the achievement and the title, I also read that everyone who did the quest before the release of WoD got the achievement. I also made a ticket and I got a reply that a GM can’t assist me with things like that and to use the support forum to discuss this issue further… So anyone is able to share his knowledge about the issue I’m facing? Thanks for your time everybody!
P.S: I did the quest during MoP and I was totally undergeared for it…I remember it clearly since it was one of the hardest feats of my gaming career, I’m 100% sure about it and never played since that expansions, just mentioning this to get it out of the way.
I got it then too, honest. No, I really did. Honest.
Seriously, they cannot check but if you use the quest checker on wowhead it will tell you if you did it and since you posted on a classic warlock we can’t check your profile.
Hi Nemosis,
Unfortunately after such a long time it’s not possible for Customer Support to verify the date that you completed the quest that would grant the achievement.
This was something that Customer Support could assist with way way back in 2014 and early 2015, but it’s no longer possible to assist.
This is the character I was talking about, I totally forgot that you could choose whom to post from. I have proof that I completed the challenge during MoP as I already replied to Ferumlac bellow. I hope this can get sorted out 
I am Nemosis, the owner of the post, this is the character I was having the issue with the achievement. I understand that it is not possible for the support to find out if I did the achievement back in MoP content. In my defence, this is the only warlock with the green flames on my account, I never played in any expansion nor I owned one after MoP, my character was 90 lvl (now 35 with the shadowlands prepatch) with MoP raiding gear and I also have screenshots of the event when I finally defeated the challenge. So if that is possible I’d really appreciate if I was given a chance to provide all the evidence I have that prove my words. Thanks in advance!
I’m afraid it is not about the proof, it’s simply a case of :–
