Because of the way her shield passive works, health stacking is actually really effective on her I've found.
Warmogs + Fmallet makes her a tank, and makes her practically unkiteable between Fmallet + Q
I also built a Banshee's Veil in a long game, which got a little silly how tough I was - at that point I had like 4k+ health (in a dps runes/spec) - so each shield was 400+ and with double E charges you can stagger them for 800 bonus health while your engaged. So, you can make a fun tank / bruiser out of her, which I think is the way I prefer to go - she's kind of odd to play as a fighter, tried it a few times and didn't like it - then once I found the tanky build I didn't bother going back.
