Is leveling broken in this game?

They have talked about streamlining some of the pre-expansion msq lines, especially the lv50 quests which filled out the end of 2.x.

Leveling is definitely much faster now; the advantage (and probable purpose) of this is to make it easier to reach the current expansion and level cap in the same amount of time, without having to resort to things like level jump items or starting all jobs at lv60.

Also: do you have a leveling buff on your server, or free company xp bonus, or an xp item equipped? If so then it will be even faster. You are probably getting the rested bonus as well, and in the future you will get the armoury bonus.

The good news is that you can try out multiple jobs and also not worry about leveling until you hit Shadowbringers. If you feel instances are too easy you can possibly try min ilvl sync.

But, what difference does it make? Even if you were at-level, those quests would still feel like fetch quests to slog through, because, really, that's what most of them are. Busy work. Most of MSQ, most quests in general, are rather trivial, whether you're overleveled or not.

There's a difference between easy and trivial. If you need to get past a bunch of mobs to reach your destination, but you can kill them without too much danger of dying, then it's easy. If you could one-shot them with an auto-attack, but don't even need to because they're ignoring your existence completely, then it's trivial. When on-level, fetch quests are easy. When you're significantly over-leveled, they're trivial.

It doesn't take too much imagination to see adventure in an easy quest that you still need to actually do all the combat for. So while easy quests may not have the excitement of difficult content, at least they don't break immersion and ruin the story the way that trivialized ones can.

Leveling is definitely much faster now; the advantage (and probable purpose) of this is to make it easier to reach the current expansion and level cap in the same amount of time, without having to resort to things like level jump items or starting all jobs at lv60.

That's the intended purpose, but they overdid it a bit. If you're leveling faster than you can get through the story (even when skipping all the extra stuff besides the story) then it's not getting you into new content any quicker. All it's doing is trivializing the content you're on in the meantime.
