It is true that for some reason target lock works.
I've had several target locked rockets (the red blips) hitting me and taking me out (at once).
I can also target lock, but sometimes the rocket makes circles around the target and explodes not hitting anything. However sometimes I had the rocket hitting the target and making damage.
Could it be if both player and target are on same ping/lag time etc. this would make a sync?
ps. stationary targets get hit more easy.
