So, there proabably aren't many Star Wars: Legion tournaments going on right now. But that actually makes it a good time to update the tourney rules, as everyone will have a chance to study up before the next time they hit the table. Fantasy Flight has done just that. You can get these updated rules and regulations now. And even if you don't play in tourneys, there's something for you in there.
From the post:
An update to the Star Wars™: Legion tournament regulations is now available through our website! These changes come on the heels of a new Rules Reference that went into effect on February 28, and today Legion designer Alex Davy is here to discuss the impact these changes will have on competitive play.
Greetings Legion players!
I’m happy to announce a new Star Wars: Legion tournament update featuring two key tweaks to competitive play.
The first and most critical change is the introduction of a trooper silhouette template designed to give all trooper minis in the game a single, standardized shape. It is frustrating to have your commander defeated because the tip of their weapon is poking out from behind a wall, or to have your creativity constrained by the need to model your miniatures with competitive line of sight rules in mind. With the advent of dynamic flight stands for the upcoming ARC Troopers and Clan Wren, it’s more important than ever to free players from these concerns.
