Opinions are usually based on facts. Seriously, open your eyes and look at FFXIV.
Ok, let's go through your post
A lot of the process of doing stuff is not actually fun (now before you whip me in fan rage, let me try to explain).
Opinion ("fun" cannot be measured using a standardized system that means the same thing for everyone, therefore opinion, not fact)
Running from point A to B is not really fun.
But it takes longer to run from say Ul'Dah to Camp Drybone than it does to complete one or two leves in Drybone.
Hey, you did get a fact there!
Sure you could teleport, but you'd waste your anima really fast.
Variable fact. Depends on how often you play. Using teleports to get to your leves seem like a waste of anima if you're on every reset, but if you're on every other or more, then it's not so bad because it'll regen by then.
Then there's the really high level mobs like the ants. If one of those ants is right in front of the narrow passage leading to Drybone, you got to wait for it to move. Which is... not really "fun".
There's that "fun" opinion.
So while the end result of doing leves may be enjoyable, I am spending more time doing not-so-fun things than I am the fun things.
This'll have to actually be surveyed amongst a large, random selection of the population to get a good not-so-fun time to fun time ratio.
If some of the not-so-fun things were made more enjoyable, crafting and DoL "minigames" for example.
Opinion. I enjoy crafting.
We get chocobos and/or horses to rent and ride places to make the run shorter, perhaps some more interesting terrain features like the rainbow in La Theine Plateau and such, then sure. More people will find FFXIV more enjoyable.
Also opinion. Public opinion =/= fact. Just majority opinion.
But right now, people have a much lower tolerance to the not-so-fun stuff you are able to ignore.
Actually, this can be a fact, but needs an actual survey to back it up. I don't think you can speak for everyone.
The people who enjoy the game, tend to play it less than the people who are not very happy with it.
Ok, can also be a fact if, like I just said, you have the data to back it up. But go figure, a game SE designed to appeal to the casual crowd appeals more to the casual crowd.
