Regarding Aurum feet vs Dusk +1, the only shoes I'd keep besides Aurum is Uni +1's for when my HP was high, and I'd swap them for the Aurums at low HP, cause I'm into min-maxing like that.

7.25 Acc, 5 Att, 2% Haste, and no losing haste due to HP/running slow make me want no other shoes BUT Aurum anymore.

Amir feet + Dusk feet + ridiculous model = ftw anyway
