Camille doesn't make sense sometimes

K first off, I'm not ranting about her being overpowered and shit like that. The only question I have is, why does her ult still remain after you've killed her?It's good enough that you're trapped with a true dmg dealer duelist that also gets shield based on ur dmg but even if you kill her you're still punished and her team comes and kills you. I 1v1ed her with kha'zix which is another very good duelist when enemy is isolated which she was and I was still trapped in that bullshit until the enemy came and killed me.

All I'm asking for is make her ult disappear when she dies,it's pretty dumb to still be trapped in there while enemies hit you and you can't do shit about it.
