A skill for a -def/+speed Brave Lyn

I'm thinking that LaD for her (A) skill can be better off than Death Blow and Swift Sparrow, but i do know that if she use LaD then she loses more def/res even though those stats are meager. Here is what im making out if this:

Weapon: Brave Bow+ (main reason why im asking this, need more power and hate that -5 speed it gives)

Shield skill: work in progress
Proc: Luna (cause its better for quading)
A: LaD (+5 to atk giving her 45, and fixing her speed back to 41)

B: Sacae's Blessing
C: whatever works lol

Now with a def bane, it hits at 14.... equals with my bride Cordelia using LaD, so with her def this low i figured it wont matter if i use LaD and her hp is low as is so i see a glass cannon style here, but i want to know what y'all think of this, see if it gives anyone an idea for there build if yall have her.
