what fradow said

@Dobas : Vog because it makes a perfect FSC armor, if you farm FSC : Vog protects against everything except the part of shadow zombies and trojans deal, so Shadow UV is perfect to fill that gap.
If you LD a lot, Skolver because it will gives you protection against GF (though not sure it's enough to get you to take one more full hit, but it never hurts).

@Fradow
The Skolver set only protects against normal, piercing, and freeze. Not shadow. If you're talking about normal damage, then both the Vog Cub set and the Skolver set are the same in normal defense. However, in LD, I see a significant amount of DA's out there. With the Vog Cub set, not only will you be protected against its attacks, but you will also attack fast enough to kill him before he hits you. The Skolver set does not give the attack speed bonus that the Vog Cub set does. Also, in the wiki it states that the DA is the most popular of all endgame weapons, endgame being 5*.

I'm sure that that error of yours was not intentional, but I'd just like to point it out.

"The Skolver set only protects against normal, piercing, and freeze. Not shadow. "
I know. The skolver set is the default set in LD, for good reasons. Perhaps I didn't express myself well on that one.
(You said that it gives protection against the GF.)

"However, in LD, I see a significant amount of DA's out there."
I see much much more GF and toothpicks than DA. Hammer and Polaris are a valid concern, but is it worth getting killed faster by toothpicks?
(That statement is entirely subjective.)

"but you will also attack fast enough to kill him before he hits you"
Depends if you get ASI UV on your swords. Or ASI trinket (especially if you are not a striker). And how much you value DMG.
(The Vog Cub set will give you a Sword Attack Speed Bonus:Very High.)

Last but not least, Skolver gives you freeze immune to Shiver. Trust me, if enough people go Vog, you'll see a lot more Shivers coming up. And freeze is arguably even more dangerous than Shock.
(There aren't many shivers out there any more. They all have resorted to Wolver stuff. Crude tools for unrefined weaklings. And they're going to stay at that, because everyone else is using it.)

"Also, in the wiki it states that the DA is the most popular of all endgame weapons, endgame being 5*."
The wiki is not always right, and there is no data to support that. It used to be the most popular because of FSC, and because Brandish used to be bad. But in LD, why spit on shadow damage (there are people with elemental resistance, notably bombers) and a chance to curse ? Unless you expect shadow protection, there is no reason to choose DA over GF.
(There is not data to support your statement saying that the wiki is not always right?

And the Brandish never used to be bad.

That is exactly the reason as to why the DA is so popular now. Since a lot of people now use the GF, most now have shadow armor, which would make the DA more effective. Also, the Faust has a chance of cursing yourself. The DA's charged attack shows more range as well, providing for more versatility.)
I have to go sleep in a while, as it is close to midnight for me.

"There is not data to support your statement saying that the wiki is not always right?"
Wiki is edited by players. Players are subejctive, and human. Just like you previsouly said "(That statement is entirely subjective.)"

DA was popular because the only T3 boss is full of zombies. And this was before Lockdown even existed.
Put it into context. See wiki history logs, check who made that statement and when. Is it recent and from a thrusty source?

"And the Brandish never used to be bad."
Brandish got a buff last year. It caused smaller (and less) explosions than now. It wasnt totally bad, but it's better now.

Anyone using the charge of Gran Faust in LD is pretty much asking to be shot.
It is ridiculously pigslow to charge, not to mention apt to vanish at the slightest provocation for no good reason. The loss of mobility would be more likely to be fatal than the fact that you just cursed yourself, not to mention that most people are sensible enough to pay attention to the fact that they're statused.
It is also impossible to curse yourself with a Faust-line if you don't use the charge.

The Brandish was once rather less desirable, due to the unreliability of its explosions. There was one point where you were lucky to get one on a Nightblade charge; two or three were the expected number on the 5* swords.

Also, in general you want to craft defensive equipment into stuff that already has the same defence type or resist type. If you want fire resistance, then you're going to want to have that stack to be as much fire resist as possible, so you can be immune. You're probably not going to want piercing defence on a piece of Snarbolax, for that matter; the protection given by that UV on its own is unlikely to make a significant difference, and there are few situations where both piercing and shadow defence would be desirable at the same time.
