I'll prepare a write up for you, Edena... your stepping into my specialist territory...
All I play are caster-fighters... whether it's multiclass, paladin, ranger, warpriest, arcane archer, assassin, psionic warrior, or anything else that can cast at least up to 4th level spells...
I should have a pretty good set-up using just WOTC products in about a day... I'll post it to this thread. Keep in mind that although my path isn't combat optimized -it is grown from experience on what you NEED to take in order to survive. I've got the experience in that field.
