If the content in the game is so shallow that the only way to keep it going long enough is to make TRAVEL a ridiculous and arbitrary grind to keep me subbed then the developers have bigger problems.
Saved games are not a necessity. They weren't for much of video gaming history. I could argue flying mounts are a necessity. Their were lots of methods in the past for continuing games without physical memory, see saved game codes or check points. Saving a game at any point is a huge CONVENIENCE and one that is almost now universally accepted.
No your experience is definetly atypical and not how the developers have designed it. How much time did you put since you hit 90? How much luck did you have? How many coins did you roll on? We need more details but the reality is to kill lfr lei shen in one day you need a pretty good mixture of time investment and luck. The caps on lfr, coins and the weekly barrens crap is proof enough of that. Even 20 coins isn't enough often. Very very few people are killing lei shen on day one at lvl 90, especially if their new to this game and especially if they don't have hours and hours to commit to it. You committed hours to it, got extremely lucky or frankly are full of shit. Hell just completing all the lfrs back to back (never mind the ILVL requirement) is a good day at least. An hour in que and then an hour for each (more likely hour and half or 2 hours).
No Blizzard did listen to the hardcores, it's just that totality of your wishes and wants are so obviously unreasonable that not all of them can be listened to. Getting rid of lfr and lfd are good examples of that. Those are obviously here to stay and it would be best if you recognized they are here to stay. Now you won't do this and instead you'll rail on about how you get ignored even though that simple isn't true. For the amount of the player base that we could label or dub "hardcore" you've gotten more than your numbers probably deserve. They have bean counters to listen to and the bean counters determine much of what goes on in the games. Like that's the best part you don't even realize how unrealistic your wishes are and when the developers (naturally) don't heed to those wishes you automatically think they haven't listened to when they've done nothing but listen to you or at least acceded to your desires far more than they should have. That's entitlement btw.. I mean that's real entitlement not what get's labeled entitlement.
