I may be in the minority on this, but I just sort of intuitively disliked Wyll at first.
I hated his introduction. The Errol Flynn pose and cringy one liner immediately made me think that he was an arrogant clown. Following on that, all of the dialog assumed that I had heard of the Blade of Frontiers before and that I therefore must be in awe of his gallantry, when the fact is that I initially distrusted him and had little to no idea of his actual deeds.
My suggestion (which may not be possible given that the voice work is already complete): Provide a dialogue option to ask "Who or what is the Blade of Frontiers?". An alternative would be an easy Baldurian knowledge check with narration that explains who Wyll is and what the Blade of Frontiers is known for.
