Constructive & Helpful!
In the case you have NSoD, you should always use NSoD, unless you only farm exclusively on Undeads, Dragons (depending on mem/non mem status and ownership of a 15% non weapon, boost item) or Humans (in the case of SDKA + NSoD), that is obvious, but I would never assume anyone has NSoD, unless I am fully aware they do.
Since you yourself have NSoD, it's a no brainer, but in the case of someone like majesticstar, who just created their account not too long ago, using the Evolved Dragon Blade is an option that I would suggest. Even if it takes a couple seconds every time you switch over to a 15% damage boost (or Dual Chainsaw Katanas, or whatever) when farming on Fenrirs, if it saves just 1 instance of the previously mentioned needing to wait for the game to allow you to input another command, you have essentially saved time and if not, the extra seconds you may save will equal out the time loss of switching weapons, easily. If you are that worried about shaving off seconds anyways, I don't think it's going to be much of a hassle to go to your inventory every now and then, if you are already fully focused on getting the quest done as quickly as possible, by all means necessary. There's definitely also a factor of which class(s) one has available and what level you are.
This is also a question of extreme min-maxing, because using a 15% weapon baseline would probably give about the same result anyways, but using Evolved Dragon Blade could save you a couple seconds here and there. If I was a member farming Blood Gems with Kiss The Void and didn't have NSoD, I would think it's worth it, if I wanted to save every second I possibly could. That's all it really is, an opinion, even if a heavily biased one, based on my own experiences.
