Jerome, although I really hate Branwen's guts, I was regretting letting her go, cuz she can do Cure Heavy Wounds, which I never got Yeslick to do. Also, my dad had some trouble w/ Yeslick where he would disappear when you left the mines or something like that, I don't know if it was a bug.
Definitely drop Jaheira she is useless. Kivan is good and also Ajantis, a paladin somewhere in the NE. he has many neat special abilities. Definitely keep Minsc, Dynaheir, and Imoen. you don't even need to dual her if you don't want, Dynaheir is a good invoker.
