The problem with SoF is that it's incredibly boring to repeat to the point people dread getting it in the trial queue. Even the Ultros fight was boring after the first time. That's the main misgiving i have about over complicated dungeons that make you jump through hoops. More interesting boss mechanics is fine but when you need to do a bunch of dumb stuff just to get there i roll my eyes. Wonderholme in Tera Online was a good example of this it's kind of fun the first time but then it just becomes a chore to go through all the motions. I prefer consistency over a cheap thrill one time that bores me each time after.

No stupid puzzles, no jumping platforms to get to switches to open doors, no BS slow sneaking around past mobs. Just none of it. Let me farm my stuff for the week and move on.
