I mean, I think them between the proximity of our release, and this one, there's a pretty clear objective in mind.
Chaos Space Marines are designed from the ground up to lose to our Loyalist counterparts. Not only does the new Loyalist codex contain hard counters to our existing strategies, but all of the buffs we received are either designed to be countered by Loyalist tactics and design, or are explicitly worse versions of what Loyalists have received.
I think it's a very clear statement from GW, that CSM products are not intended to be enjoyable within their own right, but are far more intended as a supplementary product to a LSM collection. Xenos too, but to a far lesser degree. If you're setting up opposite a Loyalist player, your armies objective should be to provide your opponent with an engaging board game, not to win. You're basically an NPC.
These releases are 100% designed to mirror the fantasy of the lore, the idea of COSTANT Imperial victories and dominance.
