I felt the same way at first. 30 dungeons later and I'm a slave to the "[" and "]" keys.
Bah! In my many years of playing, can't say I've had to use that very often. There was a period when I first got the game where I was afraid of the dungeons and tried my darnedest to avoid them. Then I got over that and did more dungeons, but I still wouldn't do underwater portions. Then I got over that, too, and I'll do any dungeon you throw at me. They're what the bulk of the game is about, really, so it's a shame to skip through them.
Every now and then I will mix things up again, and immediately use the [ and ] to find the quest target, and then I fight my way back out. Then you get a sense of the dungeon dive, but at least you have an idea of which direction to go.
