With RP it's not worth to hunt on that part, keeping sw + mid + half nw + medusas + frosts keeps on a good exp/h (500k/h+), with mages only with area rune is doable (thunderstorm because there are many eternal guardians, can make an option for this), while using SDs there you will waste tons more and exp doesn't increase that much, risk of dying. On the upcoming EK version, it goes there because it increases exp a lot with EK.
