I did a quick search, couldn't find anything about this.
What is the point of Weiss piloting the AT-ST? The AT-ST has Arsenal 2 without him right? So taking him is just an extra 10 points for no reason? Or are we forced to use a pilot for the AT-ST?
Also, when you use arsenal 2, do you fire both weapons separately even when attacking the same target or can you fire them both at the same time at the same target pooling the dice and stacking impact? For example the ms-4 twin blaster cannon and the 88 twin light blaster cannon. One has impact 3 and the other has impact 1.
