That is what I tell everyone! I won't move from where I am at if I am having a field day against the other team, I trust that who ever is behind me is not going to allow anyone to get to me and that is going to mean kills for them or him/her who is behind me. I always position myself in a static position that only gives the other team 1 maybe 2 avenues of approach to me, that allows me to focus on mine and I trust I won't get killed because I am covered from behind.
