Blood Magic / Resolute Technique Life Gain Marauder Tank

This is my first ladder character passed level 40, I'm late to the PoE game and it shows. I created this build purely to see if it would even work, but so far it's treated me well with only a couple points of friction. The most important part is the 100% focus on defensive skills, especially life gain, armor, and life improvement.

I'm open to feedback or ideas, and would love to hear comments. I created this build purely as I was going, with close to zero planning. I'm also a complete noob, so if you have constructive feedback I'd love to hear it and learn.

Quite clearly unfinished, but my plans are to focus on pure def/life/resistance. All defensive.

Thanks Y'all.
