Why does my SetActorRotation cause sluggish rotation?

Well, I notice that if I tell my character to not ignore controller pitch and yaw, then I can use the AddControllerYawInput and AddControllerPitchInput methods to rotate my character, and these rotations appear smooth - they also replicate when testing in multiplayer. So, those two methods are doing something the “correct” way.

I just don’t think I want my character to rotate entirely based on the controller rotation. I think I’d rather be a bit more manual with it.
