How fairs my Marauder? Looking to not die.

This is my Marauder through level 29:



I'm running the following gems:

Heavy Strike, Ground Slam, Sweep (only used in "oh shit" situations), Warlord's Mark, Enduring Cry (don't use but leveling up the gem), Anger (same situation as EC)

My plan is to get to the Duelist's health/regen nodes before going to Blood Magic and working on my damage modifiers. This is approximately what I am planning to be at come level 50:



I just started Act 3 Normal and am working my way into that late-20s gear.

I'm looking for input on how this will do come end of act 3 / beginning of Cruel.

Thanks =D

Blood magic is something that you use early game, but not in mid or end game. Blood magic isn't worth the auras that you sacrifice.

I've read elsewhere that going regen+blood magic+health is better than worrying about mana and the auras that come with it.
