I mean the problem with ninja LB is mostly people being greedy or not having hp % enabled on the Hud options. Travel time can be an issue as people can heal while you are traveling and live if you are too far from them. When they adjusted death linking's duration, I think they made a mistake. Should probably have been changed to charges over just a time limit nerf. It really didn't do jack shit for the top end ninja. You still get 5-7 picks if you're paying attention and time it well/synergize with your team as enemies trickle back in.
