I am firing and my teammate runs through me. I am a team killer.
blocking is part of realism.
i prefer a blocking noob in a doorway over a ghosting mate sticking in me at a window trying to shoot from same spot and killing me or get tked by me unintentionally.
Daily occurrence if you play a MG gunner.
Firing, teammate runs up from behind, passes, runs in front, bam.
You'll leave it more open and accessible to griefers though
