We're not sacrificing a damn thing, because QM explicitly told us we could still have Terminators in Company assigned squads, and if you recall separating out individual squads to assign portions of companies to different theaters is a thing we have been doing since the beginning.
If you want a giant block of Terminators, there is literally nothing stopping us from detaching and temporarily reassigning them elsewhere as needed.
1st Company isn't just Terminators! They aren't even majority Terminators in most Chapters!
The thing is I don't really understand how the 10th company wouldn't also be good at assaults. They still wear power armor and are a full veteran company. Their primarily focused on stealth sure, but they'd still be able to do what sternguard could do. The only thing we'd be missing out on is a full terminator company which most chapters don't even have. They just put what terminators they do have in the first. And we'd still have terminators they'd just be distributed differently.
Do I seriously need to spell out that you are choosing to have recon specialists instead of heavy combat specialists, and that this implies they will not, in fact, be as good at combat as they otherwise would be?
