Looking for help with a 2H Mace build wich is currently mine

Hello everybody, i'm kinda new on this game, started this league when two friends told me about the game. I felt in love as you all can imagine.
However, i'm kinda stuck at this stage and running out of ideas and asking myself if my build (wich is pretty simple atm) is endgame viable?

This is a link to my build : http://www.pathofexile.com/passive-skill-tree/AAAAAgEABS0LYRLhFE0UUhT2GjgaVRv6ITQhVSUnJd8nLyz7LdIyCTJ-NI41kjboOBs5DjpSOtg8LT38R35MsUz_UeZTu1WpVw1YY1ivXUlfP2BLYMRhIWFSZKNlTWeba9lsRm5pcmxyqXTtd-N4DXloeu97jHy7fNmE2YTvhjuGYIdqjM-QbJHOl7ScJ57FogCkGaSsp4SpaKluqXOplKyqrLquPq9stC-18rvtvJ--p7_VwQTFisbY2L3ZYdw945_kUew47hTvDvAf8i_2SPcy-TT-Cv6P

And this is a link to my stuff :




I'm using as you can see molten strike as main skill but the problem is that i dont deal enough damage and die pretty easy compared to 1H marauder's with shields. Well i do survive but still i really think its not enough.

Any help on this? Thanks a lot.
