I don’t see any countercharge threat, or any units that can do actions. You have one ability to fall back and shoot, but the rest of your army is stuck once they make contact. The list also gives up No Prisoners super hard. Even with veteran cohort rules available, I think you’ll really struggle to deal with being screened out, and your units’ huge footprints mean it’s tough to hide them. This feels like an 8e list ported over to 9e, and while you might be able to muscle through some games on firepower alone, I think you’ll have better results with a less skewed asset pool.
Just my immediate thought
