Just a bit to show what a difference it makes:
Might not seem like too much, but then you look at the bst
Base Lyn has 157 bst
Resplendent Lyn has 167 bst
But that’s not all, she also gets +5 from the extra DF
Meaning R!Lyn has 172 bst potential compared to current gen units
You now what current gen units have for bst? 172-173.
Yeah, Resplendent Lyn (and Cordy too) have current day BST.
And while Lyn’s still not really the destroyer of worlds like Shannan or Líf, her weapon has desperation on base
Meaning you can skip the rather eh Brash Assault for pure stats
Sure, her atk is bad. But she’s rather bulky accually with the right skills. Especially with that speed defending her. And she’s able to combo desperation with stuff like wrath, special spiral, null-follow up or lull.
