GW have just released a new errata and FAQ based on the new Astra Militarum codex. If you haven't seen it, you can find it on the following link

I don't normally post about these, but there were a couple of things that caught my interest and came at a good time as I was working on my Codex review. 

The first major one is the change to Commissars. Under the old rules, Astra Militarum units within 6" of a Commissar could never lose more than a single model as a result of a single failed morale test. Under the new rules: "The first time an Astra Militarum unit fails a Morale test during the Morale phase whilst it is within 6" of any friendly Commissars, one model of your choice in that unit is slain and the Morale test is re-rolled (do not include this slain model when re-rolling the Morale test)."

This has big implications for Conscript spam units in the game. Previously, if you were to wipe out half of a 30-strong Conscript squad, they could only lose a single model to morale. Now, however, you are only getting a re-roll for the cost of a single member of the unit rather than "automatically passing". This is a big change meaning that morale will have a big effect on these units and other Guard units in the game. I think this is probably a change for the better, making conscript mobs much more likely to fold under intense firepower. 
In fact, most of the time you are probably better off not including a Commissar in your army. The rule states that you must lose a single model and re-roll the test. This could be more detrimental in a lot of situations. For example, say you fail a morale test on a 1 or a 2 and would lose a single model from your unit. If there was a Commissar nearby, you would be forced to lose a single model and still re-roll the morale test, potentially losing even more from your squad.

The other big change for me was that Genestealer Cults armies now use the new Grinding Advance rule for their Leman Russ tanks, allowing them to fire twice if they remain stationary or move below half speed. As I was planning on adding a Russ to my army, this is a great boost for them, giving them much more firepower.

It is a little annoying that my brand new Astra Militarum codex that is less than 2 weeks old is already out of date, but I do appreciate the speed with which they are fixing things. 

What do you think of the new FAQ? Is it going to improve things in competitive 40k without conscript blobs tying everything up.
