Why wouldnt it work? Are we assuming the player base is so inept they cant move through one corridor compared to another? Or that they cant complete jump puzzles? Or that objective based completion would be beyond them? Im not saying make the player scale mount everest, but rather they manage to walk up a short hill at the worst.
See, I disagree. I think the opposite is gonna end up being true. Players who were vocal about it being to hard are a minority and that the player base would honestly appreciate more complexity from their dungeons. Where dungeons are a thing you have fun doing, and not a chore you fill out on a checklist. This is the problem with things being casual. There is such a thing as being too casual, to easy, to simple, to straight forward. If there's no reason to explore, nothing worth seeing, nothing fun to do, why would I even bother going over to those side routes. Way dungeons are designed now, they're just time sinks that if it were not for the daily tomestones, most people would ever bother with them simply because they are not fun to play.
Since loot is useless from dungeons, its more important to get Tomestones, and alternate paths just offer you pure trash, why would anyone spend any time in that dungeon. They turned it into a speed run by minimizing player interest, which I dont believe is what players overall wanted. Trash your own attraction, and then wonder why people dont bother visiting it.
Most hard modes in of earlier dungeons were just reused assets. And since they were cranking out two dungeons per patch and dialing it back to one, it leaves us to wonder what exactly are they doing with that extra time? So if its a time constraint that's worth while, that seems a bit odd since they should have more time now unless theyre using that time to create F/M Hrothgar/Viera. As for 'content' for players, since the broad bulk fo hte player base doesnt do savage, wouldnt it make more sense to dump time and complexity into content most players have access too. What good is grinding out tomestones in a boring dungeon if you never plan on doing savage. Even if the gear is better than what you have, most players arent so stupid that they cant see it's pointless if they can clear current dungeons without issue by being I lvl 440.
People keep saying "Give me more to do" but then we keep saying "Nah, more complex dungeons and things, no one will want that?" That seems stupid. I used to remember people cleared all of Brayflox in ARR for exp and items. They dont do it anymore cause all would be rewards are useless, and if the only incentive is "You want to kill more monsters just cause", of course people are just gonna make a straight line to the end. Why wouldnt they?
