Not sure I understand this.
How do you put content in the mid-levels of the game, when the mid-levels of the game have been reduced to a casual afternoon? It's not about "Draging" the levels out it's about having them take a semblance of any time to even finish.
As it stands the game is a hillarious blurr at how quickly you can get most of the games content done outside of instances you require the "perfect" setup to get any real reward from. Crushing the game into a tiny cube doesn't help the fact it fosters a even more hostile endgame enviroment because people are all idling at max level. Content is designed so people don't have fun playing the job they want, they "Have fun" being forced to level every single job so you can be flexable and switch to monk at the end of Aurum Vale....
So firstly I'd like to adress your "Everyone" definition. Do you mean people who didn't want to go outside of the box or do you think everyone always did those?
Last I checked one of the most popular blogs was Campsitarus (Knew the person who made it personally best guy ever) let's have a look at some of the out of the way camps thousands of players who hit the blog took their parties just to spice it up.
12-14 Meriphataud Mountains (Hill Lizard)
12-14 Maze of Shakhrami (Maze Maker)
12-14 Buburimu Peninsula (Snipper)
14-16 Buburimu Peninsula (Bull Dhalmel)
16-19 Buburimu Peninsula (Goblin/Shoal Pugil)
21-23 Carpenter's Landing (Diving Beetle/Shrieker)
22-24 Batallia Downs [S] (Lycopodium)
22-24 Rolanberry Fields [S] (Lycopodium)
22-24 Sauromugue Champaign [S] (Lycopodium)
23-25 Korroloka Tunnel (Clipper/Greater Pugil)
25-27 Grauberg [S] (Rock Eater)
25-27 North Gustaberg [S] (Rock Eater)
All of these and more, (Until the latest expansion that made leveling into a laughable event much like it is in XIV) you could enter most of these zones during prime-time and actually find a few people leveling in these places. off the beaten path because the "Standard" was either over-crowded or they just didn't feel like visiting the dunes for the umpteenth time.
WE HAD OPTIONS
Sure lots of people stuck to the tried and true camps that (In many cases were actually terrible) but were quick and easy consumption because they took the least effort to get to and complete. But the people willing to go the extra mile could, they could have a entire camp to themselves.
Now for the bulk of your post I'd just like to say that just because someone spent all of their anima and they have to wait...I don't see that sacrificing their fun they had tons of anima to spend how they seen fit. Shortcuts are cool and all but they need limitations and boundaries, perhaps this may come off as me feeling "I know better" but making people actually experience the game world shouldn't be a form of punishment. They should be forced to look at the game world every once in a while to show them that there is a game that exists outside of the towns and entrances to the instanced dungeons.
For the last part about me hiding behind a sheild of my friends, many of them I made in the game itself. I go out into my community and I am rarely "Mocked" people may find me a bit quirky but I guess it's the fact like in life I could give two ****s what someone thinks about how I play the game. If I go to a promyvion I do it with people who will play with me the way I play. When I play with strangers I don't "Fear" them, the game shouldn't have to compromise mechanics so people can never make a oddball choice that someone might say? RDM solo? You must be crazy....what an idiot never play with him.
People being unique and finding crazy things about the game should be part of it and encouraged. The developers should never streamline the game just becasue of social pressure that's a community problem not a development problem. How about you ostrasize people who try and belittle people for your playstyle and choices.
Tollerance is the worst solution, never ever suggest that you make the game streamlined so people can tollerate you and your playstyle. The community can take care of itself, we don't need the developers to play big-brother with game mechanics.
