I have a Spelltheif/Swashbuckler (and soon to be Legendary Captain), a WarPriest/Scout/Cleric, and a Ranger/Knight in the current campaign that I run. (plus a Wizard/Rainbow Servant and two cohorts. and their ship's crew) Everyone wants to be a scout, We've had Samurai, Warmage, Favoured Soul, and Dragon Shamans in previous campaigns. They're all OK, but have drawbacks not associated with the core classes (like a dependency on Charisma, and they can be hard to fit into your world). The Dragon Shaman seems like it is trying to get rid of a sweet prestige class (Dragon Disciple), So i'm not crazy about it. Also, i'm THE DM, so I did'nt get to play many of the classes, except the Warmage.
