Arcane Trickster: I hate these guys. I REALLY, REALLY hate these guys. The ability to do sneak attacks with a ready supply of spells is very annoying to me, ESPECIALLY if they put in the Elemental Orb spells from Tome and Blood, as I Expect they will.
Archmage: I don't see anything wrong with them, myself. They are not overpowered compared to Mystic Theurge, except by virtue of spell penetration. Most of their abilities are duplications of various feats such as elemental substitution, are they not?
Dragon Disciple: I hope they fix the size problems: Dragon Disciple really isn't worth what you put into it, as the Tome and Blood version stands.
Duelist: YEAH!
Eldritch Knight: Spellsword got a name change, did he?
Heirophant: I liked the PrC from the moment I saw it in Forgotten Realms. I look forward to it.
Red Wizard: nothing flashy, power wise. I look forward to it as an example.
Thaumaturgist: A summoner, huh? I would be glad to see a workable summoner, one whose critters stuck around slightly longer, and who didn't take an ENTIRE round to cast: Full-round action would have been just fine with me.
