What would you change them to?
Valgyar: Wizard slayer
He was a soldier, so the fighter kit makes more sense than a ranger.
His personal quest is about wizard hunting and his dialogue shows his intense distrust of magic. So...why give him wizard spells as a stalker?
Better rage, shows his 'berserker lodge' background. He also never struck me as being a trained fighter, and as a ranger he doesn't come across as being especially sneaky. More of a charge in front of the party screaming sort of guy.
So she isn't an 'imoen-lite' and will stand out against Edwin/Imoen/Jan. Also explains why a pampered noble who has only ever snuck out to help commoners can hang with proven heroes. I'd have her start with plenty of illusion spells to show how she snuck out. Spells like invisibility, blur, knock, etc.
No dialogue or quest ever addresses him turning into a werewolf, which is really disappointing. However he is always talking about being called to the land. Seeing as how he gave everything up for the land, the avenger seems to fit him better.
Change vampire to shade (human with a blurred image) to show that she is cursed. No clunky vampire issues messing with the story. At the end of her personal quest she can become human and lose her Shadowdancer abilities. Her overall story would remain the same, while using an actual kit and avoiding all the annoying plot issues that her being a Mary Sue causes. Plus it'd make her follow the rest of the EE NPCs in showing off new kits.
Anyways that's it for me? Agree? Disagree? Have more?
