Honestly I have to admit the quests for the Classes are really good.

I've been through...

Arcanist:
Not informative really, but a fun little adventure with a surprising amount of atmosphere and adventure. This one can really absorb you in spots.

Summoner:
Actually pretty tough in spots, but some great fights. Not really great in terms of story, but is a pretty good challenge. And in truth brings the Ascians into play.

Thaumaturge:
This one is actually pretty funny, lot of comic relief in it, and starts to go into the backstory of the Magic of the Black Mages. Really good actually but definitely on the comic relief scale. The Arcanist has some comic relief too but... the THM really takes the cake for this.


Black Mage:
This one I haven't finished but so far the actual quest has a real epic feel to it and you really start to get into it

Conjurer:
One of the best actually at giving the backstory of the Conjurers of Gridania and how they interact with the elementals. It not the standard conjurer type archetype... its wholely different... but very good. This has got to be one of the better put togather class quests and is very immersive.

Archer:
Another really good one, not necessarily a lot of backstory, but a very immersive class quest.

Scholar:
This one is loaded with backstory and exploration, even into the history of Tonberries in this game. Really an outstanding one.
