I think those changes to conscripts are going to make an awful lot of people very happy.*
It's quite nice to see GW taking note of what the community thinks is very, very wrong with the Indexes and doing something about it.
I'm not sure how the Tank buff would work though...surely damage is damage is damage? A nice rule though to keep the Valhallan tanks rumbling.
*Looking at the next 2 posts. I was clearly wrong. Personally, I think that the 4+ orders will reduce their effectiveness greatly...or at least to the point whereby the owner can't necessarily trust them. Also, as far as bubble wrap; if there is a change to the number of units you can take, or to how many units a commissar can affect, there will be a big difference. Certainly removing enough of the unit so that it is no longer in any way effective will be a lot easier.
The recycling of units is a double edged sword. Yes, 2 CPs for a 30 strong unit seems cheap, but it will likely later in the battle by which time you have had the opportunity to snipe away a few of the buffing characters, so their usefulness diminishes as time goes on.
