Been keeping up with this thread the whole time so I'm going to throw my 2 cents in.
The scout movement issue is kind of confusing in the sense of its fuzziness, I mean doesn't the BBB have higher authority in relation to ruling than the GK codex would? Kind of like Federal laws trumping state laws if that comparison makes sense.
I find it pretty over the top that all the basic troops for the GK are so cheap AND come with power weapons. What does an H2H army have to do now, bring terminators in to fight a unit of basic troops? That's ridiculous. I mean with the newer cheese out there that are purely H2H such as the spacewolves I feel like the new GK codex is trying to combat that a little, but at the same time they really overdid it. It really is going to test the stratagem of wolf players (and all H2H combat armies such as BA) here because instead of being able to go headlong into H2H more broken armies full of long fangs and such will be brought in to take care of the cheese-tastic troops. On top of that you have this unit of troops ready to assault you into oblivion and they have this complete cheese shunt? Seriously? I thought spacewolves were bad with the Twolves having fleet and being able to basically assault turn 1, but this shunt trumps that to the point where I want to know what drugs GW was on when they thought that would be a good idea in coordination with the ability to give scout. All in all, I think that although this is a completely new level of cheese being brought to the table, it somewhat makes sense in relation to the newer H2H oriented armies needing something to stop them (they went about doing this all wrong though). I believe a well built MEQ list could bring them down, but it'd take skill, luck, ability and the right build.
