Well, the others said it, and I must agree, you haven't pushed this fandex far enough, even though the potential is there.
Basically, this fandex is intended to represent an elite "The Guard is for the Guardsmen!" type of army. They are supposed to have only a few options and be numerically inferior to your bread-and-butter
IG/
AM army (both because they are "undermanned" and "worn out") but they are making up for this with gimmicks (because they are "elite") and a strong board presence (comradeship). Keeping this in mind, I would change the following:
- No psykers of any kind (Astropath, Primaris, Wyrdvane), no abhumans (Ogryns, Bullgryns, Ratlings), no weirdos (Priests, Enginseers, Rough Riders), no special characters (Pask, Yarrick). Commissars might or might not stay - they don't fit the theme (neither the "undermanned" nor the "comradeship"), but maybe you can circumvent this by replacing their Summary Execution with Fearless/Zealot.
- No special snowflake units: no Taurox/Taurox Prime, no Vendetta, no
LR Eradicator/Punisher, no Whywern, no Manticore, no Deathstrike. Possibly no Devil Dog/Bane Wolf. You want to make this army as tight as possible, so cut the flutter and never look back.
- No vehicle squadrons, only single vehicles.
- Cut the codex-fix special rules like Team Manned Gun and Recoil Absorption Equipment. They just make things awkward.
- Ground Stomp (playing too much DoW2 lately, eh?

) should be simpler: just remake it that a single model in the unit may do a Stomp attack (S5, AP5, Large Blast centered on the model, Strikedown) instead of its normal attacks at I1.
- For orders, I think you should just replace the whole bunch with the Tempestus orders (they are much better for this kind of army), exchanging Advance on Target for Run! Run! Run!, and keeping Fire on My Target and Get Back in the Fight as the Senior Officer orders.
- Give the army an army-wide special rule so that units auto-pass
Ld tests if their roll is higher than the number of models in the unit. This would represent their increasing determination as they get more and more bloodied.
- The Veterancy Traits (this name gives away what is this rule about a lot better
IMHO) shoould be something like:
1.
Sharpshooters: +1
BS all across the field (up to a maximum of 4, models with BS4 gain +1 Weapon Skill and +1 Attack).
2.
Terraineers: Fleet and Move Through Cover, re-roll Dangerous and Mysterious Terrain (keeping the second result even if it is worse).
3.
Fieldcraft: Acute Senses, Scouts, Stealth.
4.
Hardened Fighters: Counter Attack, Furious Charge, fire Overwatch at BS2. Vehicles can fire Overwatch with their S3/4/5 weapons.
5.
Mech Expertise: Vehicles have an 5+ invulnerable save and an additional Heavy Stubber. Infantry can bail out even if the vehicle moved 6-12", but they must take Dangerous Terrain tests.
6.
Evasive Tricks: Fleet, may fire Snap Shots after/before running (no restriction on heavy weapons), may move
D6" when targeted by a ranged attack or charge but can't run in its next Shooting phase. Vehicles count as WS6 in close-combat.
- For Warlord Traits, I think you should check out some of the
FW tables for
IG/
AM. Stuff like Old Grudges (Preferred Enemy against a faction) and Uncanny Survivor (Eternal Warrior) would be very thematic for this army.
- Conscripts should be an addition to normal squads, like Novices in the Black Templar Crusader Squads. Like, you can add 0-20 Conscript to every squad. Conscripts as a separate entry doesn't fit the fluff
IMHO.
- Lower the maximum number of units a Platoon can take to something like 2-3 Infantry Squads, 0-2
HWS and 0-1
SWS.
- Maybe you can add the Veteran Doctrines as an option for all infantry unit. Also, there should be other Doctrines like Slab Shields, Infiltrate, and +1 special weapon.
- You can make the Assault Chimera the base entry and just have a Fast Chimera for 65 points.
- You might want to rename Scions back to Storm Troopers, just to avoid confusion.
- Probably also include a few
FW units like Field Ordnance Batteries, Medusas, and maybe the Krieg Engineers (as a stand-in for Cadian engineers).
I guess that's all for now. Hope it helps
