Advice on Ground Slam Scion [RT+BM]

Just asking for some insight and advice on the cookie cutter ground slam build that I adapted for the Scion. Here is the passive tree with 106 points allocated:



In case you're wondering what I'll be using alongside this:

-2H Mace w/high physical damage and attack speed

-Ground Slam -> Life Gain on Hit -> Melee Physical Damage -> Fire Physical Damage -> Faster Attacks

-Heavy Strike -> Life Gain on Hit -> Melee Physical Damage -> Fire Physical Damage -> Faster Attacks

Any constructive criticism on the skill tree, skill gems, and/or gear is much appreciated!
