Started this build SFF, strictly following the guide. I made it through normal in record time. Super smooth. A little mana sustain problems, but was quickly fixed with some regen. I also found that early levels putting 4x P ruby's + MO 10 LAEK on the staff is a major survivability factor. I got lucky with TU's as I went and found the staff and Moon Wrap. Made the rest through acts 3-5 and farmed Nith a few times to get other pieces.
Overall, levels 1-50 supppppppppper smooth.
I will give another update as I venture through nightmare.
