@callidusx3 those forces may not be subpar, but they sure as hell are boring as f*ck compared to the ones in the boxed set.
It may (thematically) make sense for Spacemarine killteams to just be a single squad of the same dude, but that isn’t what you’d want to see in a game with teams that have 10 guys. Especially if the other team has specialists that can do something other than shoot stuff in the average scenario.

I sure hope that the Spacemarine faction book (or whatever GW is going to call it) has a bit more than just the bits shown by Uncle Atom in his Compendium preview …

I find it is best to be cynical with GW releases, because you never quite know when they stop supporting stuff. It does look like they’ve planned ahead for a year, but at the same time I wonder if there is anything left after this year. And all of the plans are clearly designed to please the shareholders and less likely to please us as consumers. The compendium is the Index-equivalent for this version of Killteam. Yes, you can infer a bit of rules for factions as we’re dripfed new info, but we shouldn’t have to do that if the rules were designed to expandable with new factions.

GW’s modus operandi has shown that they don’t give a f*ck about balancing their armies, because there will be new rules that will have an effect on how the game plays with every faction that is released.

I sure as hell prefer Stargrave, because the release schedule doesn’t feel like they split things up on purpose just to sell stuff. The rules may be a bit flat and the background could have been a bit fluffier, but at the same time neither of that was needed as it was meant to inspire people to create their own stuff.
