My only issue I can see with the ult nerf for Camille would be in her anti-tower dive ability.
She has a pretty average at best laning phase, might even be worse now with a lot less clear speed since she no longer gains attack speed from her E. Her ult use to be her big defense from getting tower dove at low health since she could usually grab a return kill (or at least force a back) by trapping her opponent under the tower. But now, at most she holds them for a second longer (about the time it takes to walk from a little bit passed the middle to the far side edge without being stopped. So at most you might take 2 shots in that 1 second (usually only 1 though unless you gave it time to ramp up).
So why not a compromise? Extend the post death timer to 2 seconds, but allow all movement abilities (besides just walking out) to work, as well as
