Exactly what I was getting at. In DoW it made sense. The Blood Ravens weren't a major chapter , so any actions taken by/against them could have been rationalized as them being relatively unknown and possibly not to be trusted. How are you supposed to justify that against a First Founding chapter?
"Commander what do you think you're doing! Those are Space Marines!" "Errrr...we thought they were chaos?...yeah that's it."
I do however think it would be kinda cool personally to get together in a band of 100 or so guard players and charge at a space/chaos marine fort and look to the front line of the charge and just see this Gods of war creating breaks in a sea of guardsmen while some go around them and others start trying to kill them. In my mind that would put a new and interesting perspective on things. Like "Sir they have five marines at that point....I'm gonna need 20 guys."
Personally I just want commissars. You can't really expect guardsmen to not break with out some *cough* morale encouragement. The tanks from the guard are awesome and when it comes time to push back the nids maybe offer basilisk fire support, assuming they reach a certain point against guardsmen. After all Space Marines may get the glory but guardsmen hold the line and Cadians take it.
that is because every time I see a Krieg soldier I can't help but think trench warfare, which makes me think WW1 to which my thought process pulls up images of just huge stalemates along the Maginot Line. It is more of a low expectation due to image with them mentally despite me hearing bits of how awesome they can be.
Honestly I'm an Elysian guy myself. They may not Hold The Line, but I'm a suckered for their kind of shenanigans.
I completely understand it is why I like orks, throw a bunch of stuff together and it works don't ask why it just does. Basically the more stupid the effects are the more, or wild the shenanigans I can't help but enjoy them.
