Mate - a short reminder: Anecdotal evidence or individual perception is not a valid argument.
Your perception looks strongly influenced by your preferred game mode Ground RB and your lack of sufficient Air RB experience.
Intended team killing by ramming was even mentioned in one of the last Fair Play communications.
You keep coming into threads with your own anecdotal evidence and just derailing them with wrong facts.
I myself have once deliberately crashed into a teammate (we were in a squad) and in the end he got assigned the teamkill without a single shot being fired since I rammed him from below.
Does this anectode illustrate the point well enough?
