Hello all, excited to be here. I too am attempting a homebrew 8th ed rules set!
That being said it's not as pretty as other people's but I can adjust on the fly!
I have seen and read through, even incorporated a few ideas I have seen from the other attempts into my work in progress (a big one was that the adrathic destructors I changed to match the profile from the imperial space marine weapon, rapid fire makes so much sense and vastly increases the firepower of some units).
I've had a middling amount of feedback and have only gotten one game in since I started this and it was just a 1k point game so I don't think it was very representative to make note of besides saying: Sagittarum feel like they actually mean something now!
What I want to point out:
No Hetaeron Guard or Grav transport rules yet. I don't know how to incorporate the transports in as if they are a huge expensive durable transport it kind of removes the final weakness they have. The guard are a different problem, how do you bring in 4 wound monsters like them and not make them LUDICROUSLY good and unpractical expensive?
The only thing to gain deepstrike are the terminators, who also now slot into either HQ or elite depending on how you want to take them. (I would love to play a points game where taking a vanguard detatchment of nothing but termies would be worth it!)
The Telemon is a lord of war choice. Freeing up our amazing heavy support slot (albeit it's not as crazy in 8th). I made him hella durable, and expensive. He doesn't have the same number of wounds as a knight, but his ludicrous shielding should make him hold onto the table right proper.
Check it out and I would love feedback!
