To avoid a LRF just keep moving, and stay near asteroids. The Empire frigates are the ones you have to worry about. For Jericho, the missile’s guided and has a slow turning radius. I target those, but don’t really worry about them, I’ll just notify the team. There are some good snipers who get into a good position.
Create a custom battle with only LRF’s, you’ll need only LRF’s in your slots. Then just watch for the signs of where they are when they’re firing when cloaked. For Jericho, after that missile’s fired they’re blind to you until that missile explodes.
