Now we just need new Berzerker & Noise Marine models...
From your lips to GW's ears.
Hilariously, I think Noise Marines care about this bump the least. Sure, they're more durable and get to shoot longer because of it, but the bonus they bring naturally is predicated on them dying. So they're just devastators with a built in ancient, which a lot of loyalists brought anyways. MotA probably needs to be re-imagined at this point.
For loyalists, I think veterans like this change the most, as it certainly is going to make me take a long look at Sternguard for edge uses of that stratagem they get. But then the issue is they have some stiff competition in the Elite slot, which is what made Intercessors so valuable in the first place. I just keep circling back to the fact that this fundamentally changes very little for loyalists.
Which, for the record, is fantastic. Chaos needs a boost, and they need to compete on the tabletop the way that the main antagonists of the setting should. Heretics should be dangerous!
