Well looks like salvo weapons are gone, which is ok for me since most of the salvo weapons you saw on the table were grav. Also, I wonder if they will have a rule where you can only charge in the assault phase if you haven't used a heavy, rapid fire, etc. ranged weapon, since being able to rapid fire a unit and then charge them is kinda nuts. Would make sense that you can only charge if you shoot with assault weapons in the shooting phase, like now.
