WM/WP - Questions on SoftCap and on Build Strategy

Three Questions

1) Can a WP get softcapped on defense?

2) In order to make a build that allows me to get Ball Lightening, I am looking at something like the below. I had to eschew one Single Target Attack (which is sad because they are all great), which was Jawbreaker. Was there a better choice? Is this notion sound?

3) I didn't take hasten, I just think I have enough attacks to make decent chains and putout some hurt. However, hasten does make sense with things in WM tending to feel long on cooldown...

Thanks!
