It's so sad that it's a problem. Had this been 10-15 years ago, dungeons like CM/Prae would be an absolute dream for players to run, even with the cutscenes. Chances are, those dungeons would have intentional blocks to slow player progress so that you couldn't rush through it too. It wouldn't be considered normal to SR anything... at all. The experience was going to almost always be awesome for everyone, whether you wanted to hurry through it or not.
Mentality has sadly changed and we have people who suffer from a self-imposed degree of ADD, which seems to even impact some folks who were around back then. We've gone from a gaming community that sought experience, memories, and action, to a community that's about the reward. If the reward isn't the experience/memories/actions, and it slows your progress to get said reward, it's not worth your stereotypical peers time. It's funny that we can stereotype others like this, but that's how it is. Some of us were like this from over a decade ago, where we played MMOs solo (whenever possible). A lot of these people (myself included) understand/understood that this comes at a price. You will not experience everything and you will encounter hardships that other players won't. It's our choice to do this, and again... we understood this simple fact. Today, given the self-imposed ADD audience, people can't grasp that fact. They just can't understand it. They're not stupid for this lack of understanding, they're just... ignorant.
The times have changed. Those of us that want the experience, have to seek it out for ourselves. It's currently about the rewards. It's no longer about the experience, as that time has come and gone. Short of forcing the player base to do so, the devs will not create content that our peers will find the patience to wait on you for. They will complain if forced to wait even a fraction of a second, and like anything they come in contact with, they will forget about what unique positives came from their time playing. Instead, they will simply focus on any negatives about it. The majority base is so predictable in what they think they want that it's not very funny to think about (anymore). There's a reason why memes are so funny and accurate. There's a reason why we have stereotypes that we can all relate to. We're simply too predictable. There's more money to be made in catering to the majority, so you can't quite fault a company like SE on that. We, the players, are the ones responsible for the bad behavior of our peers, and the direction a game goes toward. The sooner people understand that, the sooner change can come about.
