Today a couple of guildmates and I did Layer 8 of Torghast Skoldus Halls. Then, not knowing what we were getting into, we tried Layer 1 of Twisting Corridors. 18 floors is a lot of Torghast!
It was pretty fun, though. By the 18th floor I was doing almost 100k dps as Retribution. A buffed Wings, multiple charges of Hammer of Wrath, HoW extending Wings, HoW boosting Templar's Verdict, Forbearance buffing damage. It was pretty crazy.
It's interesting to look at how the community views Torghast versus what I think was Blizzard's original design intention. I think Blizzard wanted to make challenging solo content. The original complaint about Torghast was that the bosses were too difficult. That you'd spend a hour clearing to the boss, and then get nuked.
Blizzard responded by making the lower floors of Torghast more difficult. I believe this meant that Blizzard saw the difficulty of the end bosses as correct, and increased the difficulty of the lower floors to ramp up more smoothly to the end boss. That's the correct response for content which is meant to be a challenge. If someone is not yet ready, they should wash out earlier.
However, the community sees Torghast as a "Rextroy simulator". Rextroy is a content creator who finds crazy combinations of abilities, then makes a video one-shotting everyone in PvP, and Blizzard issues a hotfix.
Torghast is that for a normal player. They get crazy combinations of abilities and get to go hog-wild, while not really affecting anything of real importance. There's no gear, just Soul Ash, which is fairly easy to get. It's PvE, so you aren't even destroying other players. You can even do it in groups, so classes with less powerful combinations can still come along. Of course, it would be better for Blizzard to give them some interesting options too.
As a result, the players do not really want Torghast to be a true challenge. It's not really compatible with their Rextroy simulator.
To their credit, Blizzard backtracked quickly on their original goal, and made Torghast more in-line with what the community thinks it is. I imagine that when they expand on it in future patches, the emphasize will be put on new quirky and unusual combinations of abilities.
I don't think I'll ever do a huge amount of Torghast. But I think that doing one or two Layers a week is a fun change of pace, and is a great addition in Shadowlands.
