It was causing a bug that allowed you to die without taking a rez token and be able to Rez yourself during an encounter. The animation it was replaced with for now is actually “Belgian flying kick” from season 8 which was iirc the first legendary finisher animation (also the first season pass finisher animation)
The first one i think is a reference to Bas Ruten, the MMA fighter. The second one is a reference to the pro wrestler Shawn Michaels and his Sweer Chin Music finisher.
From watching this I now have confirmation, they did switch out the Final slice with the Belgian flying kick, I was wondering why my Titan was doing that kick despite I didn’t not having it equipped on her
Its not even a 1:1 exact finisher as Boot to the Head. This is an entirely different finisher If you look at them both, "Final Slice" jumps into the air immediately and kicks. "Boot to the Head" slides along the ground and kicks
