I did this clip around a month ago, and ever since I've been trying to replicate the combo. I previously believed that what you had to do, was use up one direction, then W whilst using another direction to refresh the original directions cooldown, which got rid of the windup, but after spending 30 minutes in a practice tool, this wasn't possible. Please tell me how to do this.
