Question;
If this is supposed to be a SCOUT army, then why is everything basically the same? Shouldn't a Scout Chaplain have a Sniper Rifle, and wouldn't a Landspeeder be Heavy, since it is more of a HEAVY vehicle compared to what a Scout squad would be? I'm just asking, how is it a Scout army, when nothing has really changed from the normal codex? How is it a Scout army then? Why don't you add some special units, like an Elite choice for the army (kinda like scouts), and make Dreadnoughts Heavy, and any vehicles are heavy (except for Rhinos/Razorbacks), and have a special "Fast" unit of "Scout bikes"...
I think you've got the basic idea, but have to work with the Force Organization, as nothing has changed from the codex-thus not a "special" scout army...
Sorry for the criticism...
