Bungie tried to kill the hammer
But they failed, as they were stricken down to the ground

Build for the melee damage is simple:
Middle Tree Sunbreaker, keeping Roaring Flames stacks maxed by getting kills with hammer, granting a significant buff to my solar abilities (Can't remember the exact percentage on the buff).
Wormgod Caress Exotic Arms, getting the Burning Fist stacks to max of x5 as quickly as possible for ~9x damage buff to melee.
One-Two Punch on Wastelander M5 shotgun for additional 3x damage buff on hammer hit. One-Two buff window allows for 2 buffed hammers to be thrown in quick succession.

Bungie had slightly nerfed how Roaring Flames and Burning Fists interact with each other, but you can still hit completely stupid damage numbers with the combo.
