I am not using Razorwing Blitz. In the clip, I have +132% sprint speed and +252.5% cast speed, but also experience this level of stuttering with just +25% sprint speed and 215% cast speed. I experience no stuttering when using +65% cast speed. I don't experience any stuttering when playing solo, regardless of the setup.

The issue is exclusive to running high cast speed with a squad. I can run high-strength Razorwing Blitz in a squad without experiencing anything comparable. It is extremely consistent.
