What's your source for Angron still "being a kid"? IA only mentions that all of this happened a few years before he linked up with the Emperor and assumed leadership of his Legion. Besides, when Corax or Ragnar matured much more quickly than a normal human being, I don't see why the same should not count for Angron. The way I see it, the Horus Heresy novels have beefed up just about everything, taking mythical accounts at face value rather than reading between the lines -- as the original GW authors probably intended when they included stuff like Ferrus Manus lifting an entire mountainrange and carrying across an ocean. But, this comes down to just how powerful we want to see the Primarchs, and as I said before I generally prefer an interpretation of the setting where the gap between its fighters is not as massive as Black Library sometimes makes it out to be. Also aligns better with the tabletop rules this way, considering stuff like the Apoc stats for Daemon Primarch Angron. Any hand-held weapon counts as small arms. That is the official definition. Not that I would object the fact that boltguns do more damage than lasguns, of course, but this is kind of important to keep in mind when we have fluff like the 2E C:AoD talking about just how much powered armour protects against "small arms fire". The fleet was still stranded with nowhere to go for whatever mighty thing you believe could have killed a demigod version of Dorne. Their warp drives were disabled; this is how the Imperials managed to catch up with them and recover Dorn's hand in the first place (it stands to reason it would have otherwise been taken as a trophy by whoever killed him). In TT rules, Strength ultimately means the damage of the weapon boosted by the physical power of its wearer. If a Primarch would be so strong even without such a weapon, they would not need them -- and Angron could have escaped prison on his own. And for a weapon "counted as", it's meaningless what it actually is. What matters is that regardless of what the Fists of Macragge actually are, they still behave like power fists, and that's the way their damage works. That is exactly my point. The SoS' rules did not exist before, so saying "their existence is justified because they're better at doing the same thing" is an explicitly bad argument for defending the creation of this army. By this logic, the existence of Guillimarines will be justified by them being better than standard Space Marines. This is not how Null Fields work. Consistency-wise, Sisters of Silence would have to be utterly blind towards psychic powers as said powers cannot manifest within the range of their ability in the first place. Literally any human being should be better at detecting psychic disturbances than them, on the simple basis that these phenomena actually have a chance of existing. You are correct by pointing out that this is still a difference between them and the SoB -- but that doesn't change that it is just a new rule the designer pulled out of their arse, with zero justification in the game's history. Games Workshop might just as well have given it to the SoB, but they are not the army they wish to promote.
