hc mara outline

i have very little experience with marauders, id love some feedback. specifically, when looking at making way over towards the dualist start or templar start. I figured dualist had much chunkier phys nodes on-route and the main reasons for travelling to templar starting (ele damage, mana and resists) we obsolete compared to berserker/amrour master etc.

any experienced hc maras that could give ideas/input would be helpful, specifically rough level for taking bloodmagic.
