It's been ages since I played actual pen and paper D&D, but my favorite Icewind Dale characters are Renda and Ambri Fire-eyes, a ranger and a conjurer, both half elves. I just loaded Ambri up with magic items that give her a decent AC (at least -2).
Also... Some of the classes you're mentioning are confusing the hell out of be, but I suspect that's because I'm still using my dad's 1979 rulebook.
I swear, now you're just doing it to piss me off.
