Why is Boneshatter the ONLY Melee League Start Build?

VERY Basic PoB, this is just something I threw together quickly for league start testing. Make sure Accuracy is above life for Precise Technique - Gear, Abyss Jewels, Points on Tree, Undeniable (2nd Lab) Use Berserk to finish off bosses at the end of maps with your Rage, you can also spend it whenever you gain enough rage on big bosses, since you'll lose it when they do invuln phases anyways. Use Warlord's Mark most of the time while mapping and such for rage generation and Berserk Spam, and use Vulnerability on larger bosses when you need more Damage. Don't swap to Boneshatter until you have Untiring (1st Lab) and Tribal Fury / Attack Mastery / Inexorable, make sure to swap to Ancestral Cry as well. Endgame Damage tree is the intended Softcore experience of the build. If you want to feel more durable at the cost of damage, swap the points around for the More Life tree. If you want to feel significantly more tanky on bosses at the cost of a LOT of damage you can swap to the spell suppression tree. I suggest crafting a BIG axe before doing so however.
