Well, there's also the Shandris with an elf bow model. Reforged's bow is from Cataclysm, and it's clearly not a nelf bow. Like her, it makes no sense to have a Dagren with the Ashbringer.
I also fixed Dagren back in the day, but I also modified his overall look, so that's not so much of a fix, and more of a revamp.
