In a match today, I saw that the name of my teammate was flashing on the side of the screen. What does this mean? I assume it is my teammate trying to signal me. If so, how can I replicate this?
Your teammate is trying to signal you to go to their location. Just fly in the direction of the flashing name to go to where they want you to go.
If you want to do this yourself, you need to use the Z key.
