I voted the Tyranids, because they are swarm controlled and not individual to be played by people with their own thoughts and tactics.
GW tailors their lore by sales and popularity. If the Necrons sold better they would have gotten more codex updates and the old lore would have been maintained. But they most likely sold quite poorly and so GW sent out the order to their creative team to change the lore and backstory of the Necrons for the new Codex in the hopes that it would attract new and more customers. The new lore allows people to customize their Necrons for the tabletop much more freely and they can now come up with a lot more complex backstories and their own lore for their own stuff. This new lore also makes the Necrons more easily implemented in future games and allows them an iota of personality you can tailor a story around. The old Necrons were a good foe in textform to other factions but they were pretty dull overall... and silent opinionless soulless machine slaves are not super exciting for a lot of people to play around with, clearly. The new necrons are slaves no longer. They defeated the C'tan long ago and while they still remain soulless husks of their former selves they can actually forge their own path in the galaxy now. Do I like all the new fluff of the Necrons? No. But I personally have always thought the Necrons have been a flawed faction and I honestly don't mind something new happening with them. It certainly does not upset me at least
*sigh* im just seeking to understand...as i dont. i also dont think its pointless-even if neither of us ever 'gives up' or 'gives in' or 'loses', we still learn, and its still entertaining...oh well.
Far as I see it, the old codex was written from the point of view of the Imperium. Battle logs, inquisitorial reports, rouge trader excavations etc. The new one is written from the angle of the Necrons like the other codex's (excluding the nids). They may have seemed soulless and mechanical to mankind, and largely they are, but they do posses sentience so what they are actually like was pretty much up for debate. So as far as I'm concerned nothing's changed between the new and old codex's other than perspective.
I think the only playable "race" in this list would be the tau. Sisters of battle could just be glommed onto the available sm faction, same with the IG. Really if we were going to go this route it would make the human IoM faction too diverse and far too strong.
Hence the reason they would be their own separate factions. They have their own units and fighting styles, and it's not unusual for them to clash with the space marines. It can be worked around with respect to lore, and it doesn't create a hugely over populated IoM faction.
Nids can evolve, they eat, they consume they move forward, they adapt, as mindless as they may seem their codex can be evolved their niche is evolving their army forward, maybe a brain unit better then the zoantrope will arrive someday, the mastermind that keeps them running, but employed on the battlefield empowering and coordinating the nids as a unit, wont change anything big it only fleshes out how they work and the fluff, they can keep advancing on their niche of what they are and represent as an ever flowing behemoth of beasts, with the goal to scour the worlds to live and survive as well as advance them selves further. The necrons they have no goals they are as NPC as they can be, you stomp on their planet they fuck you up or you them, thats the deal. Do they try and do something different do they try and become interesting, do they evolve, are they intelligent. Suffice to say many of this points to no, they are cold they have one goal to kill, they got a programmed list of an machine telling them what is the most prudent action to take, they are automated. They are as NPC as you can get even more superior then the nids when it comes to what race is more NPC, that is how i see them after all the talks about how people liked them remaining, no wonder they changed in such drastic ways. This is how i view it, it is merely an observed opinion you can dislike and argue back with something just as relevant i dont doubt the fact that you have very much relevant arguments towards why the change was bad, but if i was a necron player i can finally say now i can reflect my devious dark side into these necrons and slowly let intelligent, slow and cold calculated fear sweep over my enemies in my style, or just go with auto response exterminate all life i can choose. I was never interested in them, never, i always shrugged them aside, but seeing how they are now i am relatively interested, if they are in game or not i dont mind both ways heck i might even consider playing the necron race if they were ever released. What is left for us to do now is too pointlessly argue where as our stances are i respect your opinion but i believe it is wrong/right.
Nah, it doesn't work like that. Dark Eldars didn't sold shit, they went with the same codex for almost 14 years, and then they were updated, with a similar lore but expansing it, and giving it more shape. GW updates doesn't work as you think. They work as writers see fits. They don't update codex not because they are not popular, but because they have not ended the new codex. DE, for instance, were on the workshop for almost 10 years, because Kelly and Goodwin were working on it slowly. Other codex are done with less dedication, but done whenever they are done. Even if GW is a greedy corporation, writers still work with a lot of freedom.
