This is all conjecture from me though.

I'm sure someone here knows better.
My understanding is that flash scales on str from the testing I've done. Shield Oath also increases enmity at a higher rate than the damage loss from the stance and I don't think the stance directly lowers str but you can check in your character stats by turning it on and off. Regardless since flash does no damage it shouldn't be affected by the stance regardless aside from an enmity increase.
