Te he, I'm more inclined to attack them than to keep them; Uncle Sparky, Boo, wing-less-ness, my sparrow ... aaaaah!
It's the NPC's that are sending you to the shrink!
Once again, I agree with Illumina - great to be able to chop and change with an array of new party combinations ... and while I'm so agreeable, I'm with krunchyfrogg on the value of Mazzy and Keldorn. Keldorn's pretty much a regular in my parties, while Mazzy is a terrific NPC that would get a better look in if she weren't in an area that had so many draining creatures (she's not quite as accessible for brand new parties as others).
