First off thank you As for color variances warbands typically keep uniform with one another. In the Night Lords trilogy there are at least 2 marines who switch (or switched) warbands and repaint their armor to the new one (keeping it spoiler free here). While the left shoulder guard has the warbands symbol on it, the right shoulder guard is free and could sport a color of the original legion they came from. The Black Legion variances within the codex supplement (link in OP) are good examples of how armor can be customized to show which god they favor while still portraying their current warband. They could always go further though. The marine could easily sport the full look of a Thousand Son: Then with a simple color swap can look like a Word Bearer:
Kinda want them to be their own class with their own skill tree to put points in. Aren't the cultist marines all mercenary bands after a certain event? (Skalathrax/Cube of Ahirman) That's three of four the death guard don't seem to have a renegade or legion shattering event but just throw them in there anyway. As for colors let them use the cultist legion colors then unlock the main characters legion colors with signifying pauldrons of their cult elite status.
Give me a Khorne Berserker with World Eater iconography and I will play it, no matter what kind of perks or restrictions are tacked on to it.
The Black Legion are primarily an Undivided Legion, but Abaddon's decision to allow others to join the Black Legion if they want to see the Emperor destroyed has ultimately added new elements (thank you, Black Legion supplement). AFAIK, the god-specific members of the Black Legion are a mix of those who joined from other legions (Sons of the Cyclops being the most obvious example), and members of the Black Legion who have, for their own reasons, decided to join them on that path.
Yes but no one said that the other four legions can't do the same. The Night Lords who are known to shun the dark gods have had unigod worshiping marines in their ranks.
I quite agree - although there are two slightly different things going on. The Undivided Legions all have elements within them that have become aligned to one specific chaos god; whether this is embraced, accepted or shunned by the legion as a whole varies substantially depending on which legion it is. When it comes to elements of non-undivided legions joining undivided legions, not temporarily but in full - becoming members of that legion and adopting their colours, the only example of that I'm aware of in the lore is the Black Legion - indeed, its one of their truly defining differences from the other legions.
Are you saying Black Legion takes in uni-god marines from other legions where as other undivided such as night lords and iron warriors dont accept those marines from uni-god legions but still have their share of uni-god marines who originated from their own legion? I'm assuming thats what you mean and i havent come across any lore to prove otherwise. I dont think GW has really addressed that topic much. Personally i didnt even know that astartes with uni-god ancestry were ever inducted fully into undivided chapters until the Black Legion supplement came out a few months ago. I thought they were used as mercenaries strictly. Now if this is a new concept that GW has come up with, i say theres no reason they cant apply it to other warbands. My favorite legion is the Word Bearers and i love their unholy devotion to all forms of chaos but i would still really like to see them have elements within who deviate like this.
In Steve Lumpkin's last twitch stream, he was asked about the god specific marines and said that they would be addded post launch. vod here(dont remember when he was asked in the video): http://www.twitch.tv/silent0siris/b/496889740
