Well, that siderail aside, I would like to see Warp Talons as final progression for Raptors. Let them teleport once in a while, and give them a mark that allows their party/squad to do more damage to one target, but give it like a 2 minute cool down so it isn't abused. Once you get high enough, there should be all kinds of fun demon choices you can make, with downsides too. Edit: like maybe a 5% chance that all other players on the screen start looking the same for 3 minutes so you can't tell friend from foe.
