The khornbolter and the Manyslayer are decent. They are not gamebreaking op but you can take them and do well with them. Unlike the plasma pistol of slaanesh which feels like a downgrade. However the plagueknive and the plaguegrenade are not all that either. The point is that all named / special weapons for chaos outside of the plasmagun, the abbadons grace and the necrotic sword are either just a reskin, very niche focussed, even or worse compared to the regular stuff. This is intentional by design to prevent powercreep. It is not like the plague grenade is actually much worse then a posion grenade on orks. Just costs more LP ofc. The point is Chaos lacks anykind of real stuff or unique stuff over the other factions. The marks were an attempt to do so by trying to give bigger advantages combined with drawbacks to equalize their value. This failed once the meta was changed. And since the threadtitle asked for it, the last balance patches as a whole brought no real new options for chaos or changed anything on our playstyle. Most of the new toys get funneled into LSM and these toys dont come with a drawback or a mark attached to it. Even opening completely new theoretical playstyles. Grav not as a solo rambo but someone who slows for the team. Servoskull beeing a very strong buff formerly reserved to supportclasses now opened up to be common among the most played class. Giving the Apoth the option to be nearly equal to a warlock in melee. While LSM still has named weapons like their heavy bolter or the lascannon which do outshine their regular variant. If you compare that with the little our new toys do its not really worth bickering which one of our crappy toys is actually in itself less worse then the rest compared to "theirs". From a company kind of view it is completely understandable why things are the way they are. Would you rather spend your designtime on something 50%+ (twinks) of your playerbase will enjoy and create a token item for the 25-15% factions or would you do the reverse most likely upsetting the majority cause they had a round without cool new toys? This is the reason why many broken things of the minor factions dont get fixed quickly. Not because they hate them or because they dont see it as a problem but because fixing them would actually require a time investment to fix the underlying problems. Like we see in the discussion of this thread, or have seen with the ace dakka, or with the lack of eldar mods. The problem was there but it happens only so few times that its not high on the to fix list.
