Need help with a Ground Slam Champion build

Hi, as the title says i'm looking for help with a Ground Slam Champion build. More specifically, one that uses 2h Axes.

I know what stats i should aim for on my gear, what i'm uncertain about is the Passive Skill Tree.

I've made a build using Path of Building and i'd like to hear what the other, more experienced players think i should change or adjust. I'm open to all feedback and constructive criticism but keep in mind this is the first time i make a build on my own and i'm far from being an expert about the game.

Here's the Pastebin Link: https://pastebin.com/qYNDRJze

Thanks in advance.
