It's growing on me! Use it when you need to use it, line formation will get you most of the way without taking too many arrows to the knee
A trade off seems to be shield wall is so much better s a defensive stance now, very few arrows get through if any and your guys tend to rack up kills a bit better fighting in shield wall now as opposed to pre 1.5.5
I agree; even after adjusting it in the latest patch it still seems too slow. Right now I’m using circle formation when moving as it’s faster and is basically the same as a shield wall (Also I am absolutely NOT advocating for circle formation to be slowed).
