@Monty and co. (Regarding the topic of Greenskins getting this re-rollable)
Possibly, and here is me partly wish-listing, seeing as they are handing out the warscrolls for free, electronically, they will be able to update them based on player feedback?
That being said, MAYBE, depending on if they do or don't release formations, campaign narratives and the like etc. MAYBE they can even add point values if they notice the community is asking for it.
I doubt, well certainly hope not, (I haven't been around long enough to judge) that GW is ludicrous enough to release a broken game without the intention of fixing it/releasing things that patch it up in the future.
I think they might have released AoS in order to get something out, show the folks that something 'big' is coming in the hopes to get peoples attention, which arguably it has, and then pump out things.
But this can just be me being the ever optimistic and naive beardling... Time will tell.
