I finally got my Crux to drop this week. After running around with it for a while, I have to say I love this gun. That being said, I don't see myself using it in pvp at all, nor would I choose it over any other arc primary for end level difficulty pve. It's just a fun gun to mess around with while grinding rep and xp. Love the animations that occur when the head shots explode. Cool alternate firefly effect.
