I'm not that far in yet -- trying to remain PURE IN THE EYES OF THE EMPEROR, so I doubt I'll see that, in this playthrough at least. Banter is pretty good regardless, with each sergeant constantly trying to out-edge each other, haha.
Yeah, I'm not sure how that's even supposed to work. In a traditional RTS, massive infantry rushes is a basic tactic. But in DoWII you don't get more units and it's always just a handful of soldiers. In the campaign, you mowed down huge waves of Orks and Tyranids, which is how it's supposed to be according to the lore, as I understand it. Do you get tank factories as IG, hatcheries as Tyranids, etc...?
Remaining pure gives you one confusing traitor, shame but makes design sense.
