I think the only real thing to do is cut out all this detachment nonsense, everyone gets X CP
at X points and thats it
The problem with this is twofold.
First, in their infinite wisdom, GW
have "balanced" stratagems based on how many CP
the army is "supposed" to have. That's why Custodes and Necron stratagems are so powerful for a low CP
cost, while Imperial Guard get things like "Fire On My Position", which would be a criminal waste of points were it not for the abuse of refund and steal mechanics.
Secondly, using a 1 CP
stratagem on a unit of Custodes is always going to be better value than using it on an Infantry Squad. They are a force multiplier that benefit elite armies. It just doesn't seem like it due to the fundamental flaws of 8th edition making elite armies a non-starter.
I agree that CP
regeneration and stealing need to be axed, permanently.
