What do you guys think about this marauder ranger build??

I made a marauder build that is kinda like Venator's Bow Marauder build. The idea of my build is to start of as a marauder for all the health nodes and use blood magic support gems on all my skills, except for the auras. It uses lightning arrow with LMP + Blood Magic + Weaon ele dam + Life Gain on Hit as my main spell, 6 link will have chain. Single target spell will be bear trap + bear trap + culling strike + blood magic just like Nugiyen's "rengar" build. The auras will be Wrath + Anger + Grace + Reduced mana, I want this to reserve most of my mana. (optional) Spell totem + Summon Skeletons + Faster Casting and a Conductivity thats not linked to that.
