|It kind of reminds me of the 80's cartoon "Centurions".|
You will no longer be able to field mixed SM armies without resorting to an allied detachment.
So, no more can you have a Salamander Tactical squad, an Ultramarine Tactical squad and Lysander in your fielded SM army. Unlike previous versions, You can't have a "count as" Vulkan unless your fielding Salamanders for your primary or allied detachment.
For those of us with Non-traditional/non-popular armies this is horrible news. I'm concerned there won't be something to console the vast majority of SM players that field MYO chapters or, even like myself, that fields a very obscure codex chapter.
What happened to "So perfect is their understanding of Guilliman's tactics that any grouping of battle brothers can fight side by side each knowing how to finish the job."?
Actually I'm more upset for players like myself. I field Red Wolves. I like fielding Red Wolves. Mostly because they're not Space Wolves. However, MYO chapters will probably get some concept like "Pick which army yours will be a clone of". Obscure chapters, even the ones that get mentioned in the codex, will probably be forgotten. We'll be forced to make our chapter a clone too, just to get the Characters. And that's what will probably happen. All of these Non-"top 6" armies will be able to field any chapter character(s) by "This game they're Ultras, Next game they'll be Raven Guard".
Personally I think that GW is trying to sell more of it's chapter specific stuff, but it won't go the way they're planning. Not for the most part anyhow.
What do you think?
