Help with EndGame Build

The basic idea of this build is to take advantage of a two-handed weapon that counts as a Dual wielded weapon and take both two hand and dual wield nodes. Up until now I haven't had alot of problems but I keep dying and going to zero xp. I really appreciate any help I can get.

I could really use some feedback on this build. Having a tough time doing bosses right now. I seem to instantly die at times and i just don't understand How I could improve this build.

I guess I kind of expected some Human PoE Calculator would eventually come online and see this post and explain to me whats wrong with this build that has gotten me reliably and safely from lvl 20 - t10 maps. Suddenly I die once an hour and it takes me 2 hours to make back what I lost. Now I am stuck at 89. Its been a full day and I don't even see any views on this post. Guess the PoE community is garbage and this game is dead. At least to me. From my point of view.
