Every WoW community is full of people that praise visions. Granted, there are also many realists that see that they're in fact not all that great.
But it's still quite jarring that so many people praise this mediocre piece of content.
WoW content has been so bland, so boring and pointless for so long, that this junk seems somewhat exciting to people in comparison.
They don't have much replayability. They might be fun the first time and maybe the second time at best, but after that they're utterly boring. And with the timegates and cloak rewards, you're forced to replay this trash every week or miss out.
They make me very worried for Torghast, if the bar is this low for "good" content. Considering that's one of the only features for Shadowlands, it has me extremely worried we're in for a really weak expansion just like BfA has been.
