I don't think any NPC is that useless even if I don't have a use for them. I would go with Cernd though for least used and maby most challanging to be made into a powerhouse. I also use Airie alot so that means I rarely use Haer'Dilas even though he is a very usefull NPC.

Its actually probably an easier game starting out if your evil because you get 3 single classed very powerfull NPC's right away in Korgan, Viconia and Edwin. I remember strugling to utilize characters like Anomen, Airie, Jahiera when I first started playing BGII because I was too narow minded about classes and there uses. I used Anomen as a background Cleric/Healer for example, what a waist.
