Blood Ravens should only be used by Relic, they created them and they are the only ones that can expand them.
They're not really large enough - don't they only control a single solar system? Compare that to the Ultramarines, who's province is bigger than an entire faction in 40K (Ultramar > Tau Empire) or the Dark Angels who's main fortress alone is a chunk of a planet. Only the big boys get to play in the 13th Black Crusade!
The Blood Ravens are a fleet-based Chapter. They have no proper homeworld The Space Wolves and Blood Angels only control a system each. What's your point?
Wow really? 9 planets are more than the Tau empire? Really bro read the wikis a little bit more carefull and dont confuse 30k with 40k! And the size of the Rock isnt that much of an advantage ...especially against torpedoes!
When do the dawn of war games take place? That could be the reason for them not being in EC, that and relic still owns the rights, are owned by sega, and from the looks of it are coming back from the warp, with support for Space Marine and possibly continuing their work (though this is purely hope/rumor/speculation on my part).
