It's like I said a few pages back: Most people can stand a dungeon being easy the first time for the story. It's brand new, there's the spectacle of the event (stuff like the Garlemald train, for example), you have the notes to read in some of them, and so on. The problem comes from having to run them over and over for tomes since they're the most efficient way of getting them.
The solution isn't to make MSQ harder (as some have expressed and as I said, many people don't want to move to harder content, so using dungeons to "train" them isn't a valid argument, especially since there are better places to do that, like Eureka/Bozja/Deep Dungeons/Criterion), the solution is to make separate content that's just as efficient but more difficult so the players wanting harder things to do to get their tomes have that avenue. It's really that simple, and we already have it: Just make a Criterion roulette and tune the tome rewards to be comparable to the time investment were one to run Expert roulette instead.
Then if the people wanting hard things keep running Expert, they have only themselves to blame and we'll all know they didn't want harder content, they wanted to force other people into harder content, which is unacceptable. They will have their option there. Indeed, Criterion should REALLY be flexed a lot more since it's such a great system. They could even, going forward, have it be the MSQ dungeon is just one path (a specific one) in the patch dungeon, and the Criterion just have the pre-dungeon 3 paths room and the other two paths to work on, and those doing Criterion roulette instead of Expert roulette get that with a random assigned path. Basically double-dip the assets and content to get your different versions, MSQ (one path), Criterion (three paths, the standard solo/friends group thing now), Variant (the hard one, roulette will pick a path for you, quing regular lets your party pick the path they want), Savage (same as today). Devs can actually save some asset/dev time doing this, too.
Either way, the solution is to give people that want hard stuff other stuff to do, not to make MSQ harder.
