See... this is a classic example of how people confuse their own subjective opinion with objective fact.
Quests are content. Leves are content. GC missions are content. Crafting is content. And so on, and so on...
Every single activity you can partake in, from 1 to 50, in FFXIV is content. Anything the game offers for you to do that entails your character doing something (within the terms of service), such as quests, is content by definition. If you're a role-player, then even role-playing with a group of friends could be considered Content.
To be clear: Content isn't "only the things Zumi likes" - or anyone else for that matter.
That you personally do not enjoy any one, or all of those activities and would rather skip past or fly through them does not make them any less so and it is not a case at all, much less a good case, for making leveling faster so, Zumi can get through it all faster.
Now, clearly you (and others) feel that invoking the presumed agreement of "many others" makes your opinion more "right"... It doesn't. What you're using there is a logical fallacy referred to as argumentum ad populum... an appeal to popularity. Only in this case, you can't even truly claim to speak for many others. You merely presume to, to bolster your own opinions.
Further, given your statement about "getting multiple levels in any NA MMO for any play session"... very deceptive and disingenuous statement wrapped in far too much generalization.
The first, and biggest problem: You don't qualify how long a play session is. Is it an hour? Two hours? Three hours? Ten hours? Your entire assertion is based on an undefined parameter, which happens to be the basis for the assertion itself. It's really poorly thought out argumentation at best. It's deliberately deceptive at worst.
If you're level 1, you can certainly get several levels inside your first couple hours (including cut-scenes, etc).
If you're level 30 and are playing for 10 hours, you can certainly get a few levels...
If you're level 50 and only playing for 1 hour, no... you're not going to get "a few levels per play session".
And on and on and on...
If all you prefer is the end game, then do what your type always does and plan out "the most efficient path to level cap" so you can bask in the glory that is currently a few dungeons and a Primal battle. I won't be at all surprised if you're back on these forums before long complaining of being bored 'cause there's "not enough to do at end game".
