The problem is that the other option is not a great outlook either: They're not intentionally shrinking the DLC, but this is literally the best they can do with their current resources. Which would mean that not many people are working on CoH3 anymore, otherwise there would be way more content.
Or it means that their entire focus for this patch was (still) on "fix the game" rather than "add new content". I'm sure that Relic's resources are now much tighter compared to pre-launch, but it doesn't mean that their team is too small now to save CoH3
CoH2 had the "saving grace" march deployment patch 9 months post release.
Help me out here, what exactly was the great march 2014 update? I could have sworn that was the patch where they just released two new doctrines with Wehr Puma and Soviet M4C Sherman in order to promote the upcoming WFA DLC. And at that point CoH2 multiplayer was in a pretty "hated" & unpopular state because of the blatant pay2win crap going on
