Yes but the ult is on an all in champion.
For example Jarvan has something similar though you can flash. But Jarvan only has his Q and auto attacks and they're not very damaging.
Camille almost oneshots with her 3 auto attack combo that you can do in 2 seconds.
And yes this was what I was trying to explain: a super strong all in champion having an ultimate so you can't escape the all in (on top of having one of the best dashes in game). It's also really difficult to poke Camille without Camille deciding to go all in on many top lane champions. And you don't win the all in vs Camille. You just lose. It's even worse if a jungler decides to come a few times to your lane as Camille her dash and ult will always allow her to lock you for the jungle and her to kill you.
The only way to really counterplay Camille is having better all in numbers. That's why Camille will always be broken or useless. Because if there are a couple of champions having better all in numbers you can't pick her anymore since if she goes all in, she loses and the only thing Camille has is the all in.
