yeah but all the armies have special idea's and mechanics and they all get special equipment, other wise why make a book for the space wolves, why not just make one unit and just use the ultra marine book,
cause i can bet the word bearers and the black legion even though they are both undivided are going to play very different the rules for mark of chaos or nurgle(+1 to toughness) or korne (+1 to attack number) are fine for basic units but they don't cover these special units of the iron warriors or the deathguard or the emperors childern just to name a few armies and the word is armies not units
and house rules are fine in house but if i try to use them on a tournement they are gone and so is the flavor of the army
oh well i was just speaking out of my butt
Suck it up and welcome to Chaos.
If you don't enjoy the fluff, then don't bother playing.
In saying that, most of the Legions can be represented quite easily with a bit of imagination.
Black Legion - Anything goes really.
Iron Warriors - Chaos Lord, Terminators, Chosen, Dreadnoughts, 'regular' Chaos Space Marines, Khorne Berzerkers (one squad), Rhinos, Havocs, Land Raiders, Vindicators, Defilers, Obilterators or Predators.
Night Lords - Paint scheme and an imagination, these guys are too pigeon holed into 'terror' tactics to be representable by any codex really. Supposedly, people believe they are 'fast' but people are also idiots.
Alpha Legion - These guys aren't really playable in any codex, so again, paint scheme and imagination.
Word Bearers - Very representable, Chaos Lord/Sorcerer, Terminators, Chosen, Dreadnoughts, 'regular' Chaos Space Marines with Icon of Chaos Glory only, Rhinos, Lesser Daemons, Greater Daemons, Havocs, Land Raiders, Vindicators, Defilers or Predators.
Cult Legions - All these guys have unique marks, such as Icon of Khorne, and they have unique units such as Khorne Berzerkers, other than that, you imagination and the sky, are the limit, they also all have unique HQ choices.
So you see, when we act like grown-ups, stop throwing our toys out of the pram, and use our imaginations, all but two of the Legions (Alpha and Night Lords) are easily representable.
Stop whining after 'special rules' and 'fancy thingamajigs'; the Chaos Codex was written in the fourth edition and is STILL very competitive in the hands of a good general, it's just not the auto-win some codices are, and deosn't have army wide rules cause of characters such as Vulkan, Khan, etc
Chaos is a lifestyle choice, you play it because you like the look of the models and the fluff. If you don't like either of those two things, go play Blood Angels, Space Wolves, Dark Eldar, Eldar etc.
You supposed to play Chaos (and all armies really) for the enjoyment of playing Chaos.
So stop whining, and start playing and earning victories (albiet harder fought ones) in the name of the DARK GODS!!!!!!
