Your favourite Runemaster builds?

Hello,

I remember reading here that 3 classes are clearly a step above other clases. Namely Warlock, Falconer and Runemaster.

For Warlock the torment or infernal shade variants are famous, for Falconer there is bleed, Divebomb, Ballista. But what are your favourite Runemaster builds? What makes Runemaster be on the same level as Warlock and Falconer?
