Camille doe not have a fail safe press R to get back all of your health ability.
She might have potential to heal 90% of her health but only if enemies literally all pile up together in the outer targeted area of her W.
For those who do not understand she is not Tank ekko.
I would hardly consider he to be having the same issues as tank ekko who pressed R and would go back to the health he had 4 seconds before without fail or landing any kind of skill.
The only thing I feel is a bit to strong is the 4 second duration of her ult at all ranks. Having it be 3 seconds at all ranks or scaling 2.5/3.25/4 would likely be better but I am not the one who makes balance decisions.

Ekko was MEANT to be an assassin. He was never meant to be a tank that still functioned as an assassin.
theyre MEANT to go in, burst you out, and then walk/mobility away.
obviously because they are really hard to lock down.
