I have to say that now I've played 2 games using the new guard, it's a good dex, not much changed really for my army to be honest except a few slightly lower costs, but made up for elsewhere. I love that you don't 'have' to shoot somebody now if a commissar is attached, so my dude may stop being proxied as a Lord Commissar and go over to being a normal bod, attached to one of my infantry squads, probly the heavy weapons where he will be useful for making sure 'orders' go through.
