There is no simple answer to this question as it depends on a number of factors. Blades of Khorne are certainly powerful and can be very effective in the right hands, but they are not necessarily the best choice for every situation. It really depends on what you are looking for in a weapon and what your own personal strengths and weaknesses are.
Blades of Khorne are extremely deadly close-combat weapons. They are incredibly sharp and can easily hack through even the toughest armour. The downside to this is that they can be quite difficult to control, particularly in the heat of battle. If you are not careful, you could easily find yourself wounding or even killing friendly troops by accident.
Another thing to consider is that Blades of Khorne tend to attract a lot of attention from your enemies. This is both good and bad – on the one hand, they will be more likely to target you specifically in an attempt to take you down; on the other hand, this means that your fellow warriors will have an easier time dealing with them while you keep their attention focused on you. Either way, it’s something to be aware of before making your decision.
So, ultimately, whether or not blades of Khorne are good depends on what exactly you need from a weapon and how comfortable you feel using them. If you want a powerful close-combat option that is sure to strike terror into your enemies’ hearts, then they could be perfect for you. However, if you prefer something a little more controllable or don’t fancy being targeted by everyone on the battlefield, then there may be better choices out there for you.
