Honestly a little disappointed they didn't go further with these weapon refines but at the same time, these refines are still good? Like I want to be more disappointed but also Slaying on a DC weapon is absolutely nuts so I'm happy for my units. Obviously Legendary Ryoma is the biggest winner of this update but Bushido II is a big part of that so things were always stacked in his favor, NFU on Raijinto is just icing on the cake.
It really cannot be overstated how incredible it is to have slaying on a DC weapon though, Ike/Legendary Ike and Black Knight/Zelgius are honestly pretty big winners this time around too and it's absurd to me that people think Ike somehow lost out here?? Having 1 charge Radiant Aether II is pretty insane and helps Legendary Ike's damage output and sustain immensely, and more importantly it means he can reliably fire off Aether without running a breath skill. The last part is huge because R Duel Infantry 4 is his best A slot for Arena anyway but even outside of Arena it gives him fantastic build flexibility without being stuck using a somewhat dated A skill.
Even regular Ike is in a pretty decent spot though because Slaying is that good, gives him some pretty strong potential with Brave Lucina to reliably fire of Bonfire or Sol as an AR carry. Obviously Legendary Ike is a stronger unit overall but that was always going to be the case with Radiant Aether II. Regular Ike's higher Speed is not to be disregarded though, especially as a carry in AR, so he's perfectly fine as a unit now.
Black Knight/Zelgius really only needed Slaying, anything else was icing on the cake but I don't think I need to explain why 2 charge Black Luna is insane. I wish they didn't give literally the same thing as Ike though I guess it's fine from a lore perspective so I won't complain too much.
Xander's refine is actually good, I'm honestly surprised. Anyone with R Duel Cavalry 4 sitting around can realistically make use of him in Arena and that's not bad. What is bad is that Xander needed way more than just a good refine, this dude's stat spread is still god-awful so he's not making an impression with only a good refine. Still, he's like usable now which is probably about as good as you can hope for.
...aaaand Gradivus just kinda sucks. A Sol Lance kind of refine is not surprising but it's really not fixing any of the problems that Camus or Hardin had, a little disappointing since I would have liked to build Hardin but oh well, can't win them all I guess.
Overall this refine set went about as expected even if I wanted a little more, Ike, Ryoma, and Zelgius/BK are all big winners here while Xander, Camus, and Hardin kinda got the short end of the stick. The only surprise for me is that Xander isn't the biggest loser here, he'd be a winner too if his stat spread wasn't atrocious.
