It's not that Monks are horrible - Princesses are simply more useful in some situations,
and those situations tend to appear a lot (especially early in the game, from what I've heard).
Also, useless classes:
Farmer - Doesn't really do anything that makes him a Must-Have.
Zodiac - From what I've heard, they're pretty bad in the late-game - though subclassing intelligently might solve this. *Wink*
Gladiator is also kind of useless. Sure, he's strong, but he hasn't got any handy skills.
He's more kind of, if I may quote Scy, "Derp I do damage" .
There are other classes that hit less - but not radically so - and they've got better skills.
There you go, three useless classes. And that's only from the top of my head.
...I do agree with you, though. :3

Monks can be put in the front line to punch the crap out of things.
Hoplites use spears and have a few decent attack skills, they can also swap from front/back using an attacking skill.
Also, keep in mind you'll have subclasses too which grant even more variety.
[EDIT]
Prince(ss) doesn't make the Monk obsolete.
The Monk still has all the active burst heals and a full party burst heal.
Also an in-battle ressurect skill.
The Princess on the other hand has a passive party heal (as long as she has full health, it doesn't work otherwise) a passive after-battle heal (if she's still alive) and a heal as you walk passive.
Depends on how much control you want with healing.
Course, you can just subclass one to the other and you'll be covered from all angles, haha.
True, true. Revive certainly is handy - but if you play with caution, you'll probably make it to the Third Stratum without dying at times where you need party members to be alive - Bosses etc.
In normal battle - or outside of it - you can just use a nectar, and everything'll be chocolate and rainbows.
After the Third Stratum, you can subclass someone as a Monk, and then you are, indeed, covered from all angles.
Especially if you subclass the Hoplite to Monk, seeing as she's got mad defense and all.
