[Baron Spikey]

Both scattering blast weapons and LoS through friendly units have been changed recently (remember these are still rules under going play testing).

BS now determines how much the weapon scatters, you minus the firer's BS from the inches that the weapon would scatter (e.g if a weapon scatters 4 inches and it was fired by a Space Marine then it counts as a hit).

You can now fire through Friendly units but the enemy gets a 4+ cover save if you do, but it works the other way to- if they want to hit one of your units that is behind another one of yours you get a 4+ cover save as well.
