Lightning claws should be in the game but not for Assault, the only primaries lightning claws we've seen have been for Phobos and Phobos adjacent models (bar sword brethren but they're black templar and don't follow rules).
So lightning claws should be added as a vanguard and sniper burst damage melee weapon, imagine doing a vanguard grapple into a superman lightning claw punch or a camo cloak claw jump attack. Plus, the modern primaris claws are retractable into the arm plate so it still makes sense to hold primary weapons and pistols
Also it doesn't work with assault's ground pound cause that would break the claws lol
Let me know what you guys think, what cool attacks could this open up for the classes and can you think of a way to make them work for another class?
