Legionary Assassin parties used to only appear once in my games. Now they come after me repeatedly. I've been attacked three times so far. They also seem to have been beefed up a good deal, carrying Trail Carbines, Thermic Lances and wearing Centurion armor at very early levels. I'm not new to the game by any means but they've become a major annoyance, so...
How do I get them to stop coming after me?
