That is so close to being amazing to me that it's actually mildly irritating.
Of all ponies to stand beside a silent yet agilie, precise, and all around ballsy as hell assassin, they chose Fluttershy.
The arts perfect, they chose my favorite Borderlands 2 class, and then they went a chose a pony who's such a heavy contrast it just makes no sense. Just a personal thing, artistically the thing is glorious.
I kinda hope the person decides to do the others, because while I don't think Flutters fits any of them, she contrasts less with the assassin than she does with the others. And I really hope to see Twi with the Siren.
