I was using hardest as an all inclusive word. We don't necessarily know what the puzzles are going to look like but it took the best players in the world 8 hours to beat Riven alone. I know because I watched and sure there are many variables you could use like they were fatigued and maybe if they got there earlier maybe it goes faster. I'm glad you referenced SoS because its one of the least beaten raid in the game both because the loot wasn't there but there were a ton of hoops to jump through in the final fight. Everyone had a job and had to keep it together from start to finish. I wish it wasn't in the DCV to see if it's difficulty could test today's sandbox and the types if players that now make up the majority. I want to caviat with I've cleared every raid when it was the current standard multiple times and beat LW like 5-days after it launched and before any cheese was found. I'm not pulling info off of a video a forum post. To date imo SoS and CoS were the the most mechanically difficult they have ever come up with. There are a bunch of moving pieces and your whole team needs to be on point.

The reason I mention spire of Stars is due to the fact that Bungie is using it as its benchmark for the Final Shape Raid. Not Last Wish. That’s the reason I make a big deal about separating the two forms of difficulty. Spire is the only Raid to keep a consistent difficulty past the Day 1 unlike raids like Last Wish, which quickly became easier due to understanding the mechanics and thus, not having to focus on learning them. People became proficient in the mechanics, and thus, the raid became easy. With Spire, even if you became proficient in the mechanics, it was still “difficult” to perform, thus making it harder post day 1.
