Well, with regards to #1, it looks like in this edition you don't have to spend the minor action either. But, you're limited to only 2 targets rather than multiple attacks not having a limit. Now, as an aside, how do you handle the combination of wide bursts with the multiple attack action? Yeah THAT'S sticky in a way that I don't think the FA rules are

And IRT #2, it all depends on the soak pool(s) of the target(s) in question, doesn't it? Body 2 is the "average" value for NPCs, and most NPCs won't have bone lacing or such for more dice, either. Assuming I hit each time, I'd rather inflict a DV multiple times vs 2 dice each time rather than DV +2 once.
