Predecessor Builds > Feng Mao > The New Hotness?

The idea of this build is to win trades for free, outfarm in solo by virtue of having infinite mana, then rotate out with just enough tankiness to be able to dive. Everyone always starts Mindrazor for mana sustain, but I don't think it's as good as the buffed Resolution. Shields seem extremely prevalent right now, so Demon Edge instead of Nightfall may be desired.
