Camille Ultimate is poor gameplay design.

Camille's R Hextech Ultimatum is just terrible design as it stops everything from escaping it including unstoppable ultimates such as R R and heck even R whose whole ability is designed to prevent being stopped by ANYTHING, yet now this ability exists which will allow her to completely nullify unstoppables.

Now you might be asking whats the problem with that? the problem with it is that this ability inherently removes important core aspects of certain champions kits and more importantly most of these champions power curves are weakened or punished in some regard to have the right to use an unstoppable ability! yet now there exists a champion that disregards this completely ruining their power curves.

So does that mean i think her ability should be as worthless as jarvans ult? of course not! however high cost abilities or skills that specifically say that they cannot be interfered with should BREAK this ultimate when used such as Vi ulting a mage or carry to escape as a reward for using her skill in the right moment as a show of skill, or a malphite burning ultimate to escape or engage.

In short champions with unstoppables should be rewarded for the proper use of such an ability and a champion like Camille should be punished for wasting her ultimate on someone with such an ability but rewarded for timing it right or using it right after a malphite or vi ult, i mean think about it her ability pushes everyone besides the target away so what could have been a great engage for malphite or vi turns into a 1v 5 suicide due to smart gameplay around established mechanics without ignoring other champions powerful skills just because it is inconvenient for riot to code it.

TL;DR: Unstoppables should break Camille ultimate binding effects thus rewarding the wise use of an unstoppable, or Camille holds her R until after unstoppable is used pushing away all enemies to quickly burst down the now alone unstoppable user dooming them to a quick demise, skill rewarding on BOTH sides instead of one sided favoritism towards Camille.
