I felt the same way about the Nightbrother Warrior - at last, something different! But the more arduous these Black Series exclusives are to get, the more I don't feel like putting in the effort to get them.
If I happen to see it in a GameStop store I will probably buy it. I have some confidence that it will because I've been seeing Zaalbar, the Rocket Trooper and the Flametrooper in stores.
