honestly though i cant see why the dark angels are in EC. They are more focused on correcting their own wrongful doings then they are doing the Emperors work in 40k. The sons of Dorn should take precedence over the sons of the Lion. (Imperial Fist or Black Templar's) With that said and no hard feelings meant i would choose the Blood Angels as my fav out of the 4.
the Ultramrines only do what is necessary to keep the human race alive, if you don't like that. then as my father all ways says "tough"
And this is something that will always annoy me (and it's entirely my own fault). The Wolves and the Thousand Sons are dead even as my favorite legions. Normally I like to have someone to focus on as 'the enemy' but I've had to get used to being on both sides.
If I can get a Land Speeder and keep a "Speed Kills!" macro, I might lean from Blood Angels to Dark Angels....maybe.
