​Do you think the Neo-Volkite is better and more viable on Lethal since the latest 5.0 Patch?

It is barely "better and more viable" on ruthless. Maybe if the target lock worked it would be good but currently target lock does not work when moving (character's arm is moved off-target if I move my camera as if I were using aim as opposed to target lock) giving it a more generous weakspot hit-detection would help the weapon a lot. The actual damage it deals is good but it needs too much time on target while getting swarmed/shot at to be viable on anything but -thropes and stuck carnifexes.
