Seriously! Who wants to play smurfs. I'm so sick of those damned Ultramarines.
Ok... I'm trolling a little bit here.
Why are we all up in arms about a game we know almost nothing about?
We barely understand the basic game, let alone what will happen with expansions and such down the road.
No matter what, in order to make a fully playable card game, FFG was going to have to leave something out of this starter box. Especially when making a game like this with all of the history and factions that the 40k franchise has built up over the last 20 years. They have shown time and again, that they are willing to add more to their games as time goes on, in fact that's what keeps these games fresh and good. Sometimes they do that well i.e: Diskwars, Call of Cthulhu, Invasion (High and Dark Elves), and sometimes they do it poorly i.e: Invasion (Vampire Counts, Skaven, Wood Elves, and Lizardmen.)
Personally, I am cautiously optimistic about this game. I'm not going to go too crazy about any part of it until I know a little more about what they are going to do with it.
