There is.
I've played in competitive maelstrom tourneys, and they always write their own deck which just removes cards that are unscorable, and replaces them with interesting cards.
Oh, I'll just leave this here: https://m.facebook.com/story.php?story_fbid=1851315258522438&id=1575682476085719
Whaaat why. WHY, GW. Why do you always have to complicate things.
So I should add point cost of Target Lock to a model that doesn't list it as it's wargear, but has an ability which is named Target Lock and has the same text as that wargear's ability? I hate that. No logic.
Ok, I'm not fixing anything until they FAQ it officially in a document. I call bullshit. The first page of every index describes explicitly parts of Datasheet, and 5. Unit Composition & Wargear says
This tells you what models are in the unit and covers the basic weapons and equipment the models are armed with."
(emphasis mine)
Then we have 8. Abilities
Many units have exciting special abilities that are not covered by the core rules. [...]
In every Points Cost appendix they state then:
[...] Simply add together the points values of all your models, as well as the wargear they are equipped with, to determine [...]"
Ok, so what about this:
Deathwing Knights (Dark Angels)
Composition:
Each Deathwing Knight is armed with a mace of absolution and a storm shield.
Abilities:
Storm Shield: Models in this unit have a 3+ invulnerable save.
Colossus Bombard - missing points
Colossus Bombard - no default wargear
Colossus Bombard - missing Explodes
Colossus Bombard - missing Smoke Launchers
Colossus Bombard - missing Vehicle Squadron
Colossus Bombard - Pintle mount not min/max 1 choice
Salamander Scout Tank - change Scout vehicle to profile ability instead of rule
Arvus Lighter - weapon choices should be entry group, max 1, have "two hellstrike missiles" and "two twin heavy stubbers" as selections with nested entry for each, with min/max 2 constraints
Valkyrie - no default wargear selected
Weapon point cost fixes
Autocannon 15 pts not 20
Heavy bolter 8 pts not 10
Twin Autocannon 25 pts not 33
