So. Camille's mobility, and how to fix it.
So first, I haven't seen much Camille. She's banned in pretty much every game, and when she isn't she gives very good reason to ban her. Sure, she's a tanky, high damage diver which is always going to elicit some complaint. But the main problem that I see with her his her mobility.
The devs did a good job with the concept, and to some extent with the execution. It feels like you're swinging through the air like god damn spider man and that's pretty cool. But balance-wise, it's a bit iffy. Mostly because, much like Talon, she can catapult herself over walls with little effort. Talon's parkour is already considered a bit dubious, and Camille doesn't have the cooldown that he has when crossing the same terrain piece. This allows her to dance around and over the walls as much as she wants.
Here's an easy solution: Make it so that her launch direction is limited to the surface she's already on. You know, like if she was actually hooked onto a wall. This would make her more balanced because she wouldn't be able to catapult herself over any obstacle at will.
Then again, Vi's vault breaker is similar in nature. And that seems ok in her kit. So make your own judgement. I'm not here to tell you what to do.
