Arcane Archer: Has lost usefulness with the revision. The "arrow +x" everodd level should be replaced with different abilities. Maybe keep "automatic magic arrows" at 1st level and add +1 to arcane spellcasting class at levels 3, 5, 7 and 9. Rate: C-
Arcane Trickster: Ranged Legerdemain is just awful. Far better would be to allow an AT to use Disable Device, Open Locks and Sleight of Hand through a "mage hand" spell, with a decreasing penalty. That way, an AT can load up on "mage hand" if he wants to. And Impromptu Sneak Attack doesn't quite float for a class that is supposed to focus less on combat than a straight rogue. Rate: D
Archmage: Good class, with nice flavor and abilities. It's a fine 5-level class. Rate: B+
Assassin: Good class, has flavor and losing the spellbook helped. Rate A-
Blackguard: Good class, with lots of flavor. Rate: A-
Dragon Disciple: Moderate class, with lots of flavor. Rate: C+
Duelist: More flavor than anything else, but precludes the rapier+main gauche fighter. Excelent for a city rogue. Rate: B-
Dwarven Defender: Incorporated some of the 3.0 epic DD to make this class a wonderful choice for dwarven fighters. Deadly in the right situation, and just as effective as a regular fighter in other situations. rate: A-
Eldritch Knight: Bland. If you take 5 levels of fighter and 5 of wizard, you get, over 10 levels, average BAB, almost-good Fort and Ref saves, +5 spellcasting levels, one metamagic feat, increased familiar powers and 3 bonus fighter feats. The EK doesn't add anything interesting to this mix. Might as well stick to Ftr/Wiz. Rate: E
Hierophant: Nice abilities, but wouldn't float as a 10-level PrC. Good thing it's 5-levels. Rate: B-
Horizon Walker: It should be clarified if the HW needs to visit the prospective terrain at least once before chosing it. Otherwise, it's just silly. But if it enforces the "walking" part, it's a fine class. Rate: B+
Loremaster: Very good class in 3.0, and still is. Rate: A
Mystic Theurge: There's only so many spells you can cast in one round. The MT has ultimate versatility, but in the end isn't overpowered. It just lacks flavor. Works best for clerics of Boccob or similar magic gods. Rate: C
Red Wizard: Looks like a good class, but I'd rather have a Greyhawk example of a setting-specific class. Rate: B
Shadowdancer: Very good class, with tons of flavor. Wonderful for rogues, monks and rangers. Rate: A
Thaumaturgist: Seems too limited in benefits, but has to be tested yet. Rate: C- (pending).
