Wow, lucky! It depends on your question, I think.
Once I got stuck, like, legit stuck in a bottleneck quest so that I couldn’t continue the game at all over a dumb bug that -according to wowhead- had been there for years, which was a full day waiting for me to even get a standard answer that I’d have to figure the quest out on my own.
So I reposted again, with the same info again, including the wowhead link again and a tip to google my problem so they can actually see what I’m talking about. Took them another full day to answer.
Then I finally got a gm ingame talking to me, to whom I had to explain everything in detail again, even though I just repeated what was in the post and that if they didn’t get it to follow the wowhead link to get a better explanation. It’s all bloody there!! It took me a long time to just convince the gm to look at it because I really couldn’t continue and it would result in me having to delete the character entirely. That kind of stuck.
Then he/she started messing around in the quest themselves, realizing that it really was undoable and because of bugs and then, finally, they were allowed (and I want to stress this because their hands were obviously tied by blizzard rules!) to put me past that quest but not without a warning that they were not really allowed to do that but because I was really entirely stuck by a bug they could make an exception.
I was also offered something in a different blizzard game(?). I said I don’t play other games, but that I didn’t want a pet anyway. I want blizzard to solve obvious bottlenecking quests that bug the hell out. Up to that point (goblin starter area) I had already run into a bunch of other bugs that I could work around, but this one broke not only the game, but me. It felt like a crappy f2p game tbh, because of all the bugs.
And the answer was that Blizzard’s policy is to not fix old bugs at all, but focus entirely on the new expansion alone. So not even gamebreaking bugs are addressed, hence why you see posts about them from years before.
I could give more horrible examples but I already have a wall of text. My average is about 2 days waiting time in the later expansion, while a few hours at most during wrath. And “character stuck” was addressed almost immediately back then.
This quest:
If you scroll down a bit you can see a post in 2014 by ferana complaining about a likewise problem. For me thrall wasn’t there ever (I tried a few times) so gally would focus on me solely, even the gm couldn’t make it work.
edit: Hey, I can post links again!
