The new WD article saved me about 100 points but also forced me to drop an inquisitor. I'm thinking of using this list now.
Vanguard Detachment (Inquisition):
Inquisitor Coteaz (Warlord)
Acolytes x6 - Stormbolter x6 and Ordo Malleus
Acolytes x6 - Stormbolter x6 and Ordo Malleus
Acolytes x6 - Stormbolter x6 and Ordo Malleus
Jokaero Weaponsmith x3
Spearhead Detachment (Inquisition):
Inquisitor Karamazov
Ambull x2
Inquisition Land Raider Prometheus - Ordo Malleus, HK Missile, Multimelta and Stormbolter
Inquisition Land Raider Prometheus - Ordo Malleus, HK Missile, Multimelta and Stormbolter
Inquisition Land Raider Prometheus - Ordo Malleus, HK Missile, Multimelta and Stormbolter
Execution Force Vanguard Detachment:
Callidus Assassin
Vindicare Assassin
Eversor Assassin
Culexus Assassin
Essentially, I used the points to add hunter killer missiles to the land raiders and add two ambulls (proxied by ambot models) to the list. I don't expect it to be super competitive but I can win a game or two at an event and it is fun to play. I want to add a third inquisition detachment, instead of the assassins, in order to be truly a pure inquisition force. However, that means adding more inquisition units and, probably, a third ambull, just to fill points. While daemonhosts have certainly improved, I'm still not a big fan. Plus, I'd probably have to add an assassin via strategem for points. Either that, or I look into giving things like acolytes plasmaguns.
