What's the primary issue, the detection of Samira W or the line after which the Jhin W should exclude targets?
I don't know the exact specifics but essentially Yasuo W creates and destroys minions very fast when it interacts with Jhin W in order to simulate the projectile. Samira W would have to do that in a circle, while moving dynamically which just... isn't as feasible. We would likely have to come up with a new solution.
