Is my build based around Molten Strike viable?

I am new to Path of Exile and planning a character based around 2h maces, molten strike w/ life on hit and life steal. I really hate to ask this question but I do not want to just copy someone else's build. I'm trying to make my own but I don't really know what to do.

I don't know if my plans above are good or not, but I have in my mind's eye a fire marauder with cool fire cosmetics and I want him to be using Molten Strike. I just hope it's viable and my build above can work. I would welcome any feedback.

Edit: I made sure to get Point Blank.
