A sniper hits an AM officer, even rolls a 6 to Wound... and yet the Officer can keep running around and shouting orders unimpeded despite suffering something like a headshot, or at least a critical injury that would have killed an ordinary human twice over? That level of immersion is also important IMO.
Just to confirm, you understand that from my (and I think Smudge's) point of view, the officer didn't actually get shot, right? The to-hit/wound/etc. rolls that caused him to lose a wound were an abstraction reflective of a sniper trying to kill him and basically causing his luck/options to run thin.
Regarding your miscellaneous changes, I'm probably onboard with most of this. I like models with higher
WS being harder to stab to death. Restricting wound allocation to a 3" range might get a little weird if you're also reintroducing the idea of attaching characters to units. Modern
40k is set up in such a way that you generally only have a single injured model in each unit to track. Not sure if this change would actually break anything though. Can't think of any huge implications off the top of my head.
The statlines you've presented are the part that I'd be worried about. A few disorganized thoughts:
* To confirm, does this unit as a whole benefit from Look Out Sir? Like, can my chosen/lord unit be targeted if they're standing behind a horde of cultists?
* If the chosen/lord *can* be targeted, then they're in pretty much the position I worried about in my previous posts. I can kill 10 wounds worth of marines. I do it all the time. Paying 50-70 points for a lord and extra points per chosen over a normal marine or a bunch of cultists actually just makes them less of an asset overall. They maybe even start slipping into active liability territory where you'd rather just not take a lord at all rather than wasting points trying and failing to keep his unit alive and deliver them into combat. If I was forced to field a lord, I'd probably spend as few points on his unit as possible and have them cower behind a building all game. Giving the last 2 wounds in the squad
FNP doesn't change that for me. (Although I like the vibe of the god-specific mechanics you've proposed.)
* If the chosen/lord unit as a whole benefit from LoSir, you might be onto something. You essentially end up turning your lord into a 10W unit that loses offense as it loses wounds. Sort of like a vehicle/monster with each model in the squad representing a damage bracket. You'd have to be careful not to make such units too killy though. Imagine a squad of bladeguard or incubi or whatever that can't be shot at until you've cleared the 40-60 wounds worth of cultists/wracks/intercessors in front of them.
* At the risk of getting into the weeds, the Lord of Chaos rule as written would allow the aura to come from the entire chosen unit meaning the aura is quite large. I'd worry about large auras like this encouraging players to go back to bubbled-up armies that we've finally moved away from.
* It seems like formatting retinues in this way would be pretty limiting. I want to have the option to have my chaos lord hang out with cultists or bikers or warp talons or raptors or possessed or terminators or havocs as well as chosen. But it would be pretty unwieldy to have to make a retinue version of each of those datasheets. Similarly, I don't want to be forced to field chosen just because I want to field a lord.
But if the unit a character is attached to *does* gain LoSir, I'd worry about creating abusable untargetable units. Like, you probably don't want a custodes bike captain to make a retinue of bikestodes untargetable. But if the unit a character is attached to *doesn't* gain LoSir, then see above about it being pretty eays to kill 10 wounds worth of marines.
