Would a Stance be better on L!Lyn?

I slapped fury on her. Didn’t like laws of Sacae and fury increases her Res so she could use ploy skills. These are some stance skills I would use: Mirror Stance and Kestrel Stance.

For full EP, Laws is probably the best.
It's +4 to every stat, and getting enough allies around shouldn't be too hard.

Many people dislike it because it's just enemy phase.
And since Lyn will often be able to take a single hit, but not more, going for Fury+Desperation is often better.

I do think Laws has it's uses if you want to focus on EP.
With the laws + mulagir combo she gains 9 atk/spd, 4 def and 7 res. You can combo that with a distant def seal.

This way you'll have a great allround boost in the enemy phase, at the cost of kinda sucking in player phase

Stance will give you +6 to one stat or +4 to two, while Laws of Sacae gives you 4 to all for having at least two allies close by, which shouldn't be hard on enemy phase, especially for a ranged unit.

Why would you prefer a regular stance?

For endphase Laws of Sacae is optimal enough. Stance skills only offer +4 to two stats anyway. Currently testing my newly obtained Green Bow Lyn (without merges and just her base kit) on a mixed team of NY Camilla, NY Azura, Brave Lucina (ally support with Lyn). With Drives and Spurs she can become durable enough to take a hit.
