[SSFHC] Roast my Thicc Boneshatter Jugg

I've been PoB warrior'ing for awhile and I think I've settled on my league starter.

Main criteria was melee, strong overall build (mapping + bossing), and tanky as possible. Was thinking boneshatter slayer, but I avoided it for a couple of reasons; Vaal Pact annoys me and Slayer needs it to be acceptably tanky, and Slayer is kind of bad at bossing without very high investment. That being said, I love the Boneshatter Playstyle, and as a long time HC player I have a special place in my heart for Juggernaut. Juggernaut also deals with trauma stacks very very well.

After review, Jugg has very strong synergies. Undeniable plus Precise Technique enables hyperscaling, Jugg regen is very good at countering trauma, and Jugg has lots of tools for getting tanky including the new Unbreakable Node. With pedestrian Rare gear, build is quite capable. Around 400k mapping DPS without consideration for totems, tanky as hell, and around 1.5 million boss DPS with Totems + Berzerk + maxed out charges + maxxed out pride spell totem. Average boss damage more around 700k with middling charges (including expired frenzy) + no vaal totem / Berzerk + minimum pride.

Average rares mean you're quite tanky. For example, vs Shaper Slam & Maven Memory without flasks, no molten shell on shaper, and only self cast VMS on : https://imgur.com/a/JbZBRx0

Main weaknesses to build imo is the latest campaign / white tier mapping. Until you pull everything together, Jugg is kind of weak as the ascendancy lacks upfront power compared to others. At league start, this is disadvantageous. Also lacks reflection mitigations.

There are a number of huge strengths however. Jugg + Rage runs very fast. Unbreakable grants a low investment equivalent to Melding when combined with Soul of Steel and Prismatic Skin, which is a decided change from before where Jugg was weak to Ele damage. Undeniable c/w Precise Technique means every point of strength grants you accuracy higher than life, life, melee added damage, and attack speed. This is multiplication on its own, but if you add the fact that this means more trauma stacks as well... the scaling quickly becomes relatively insane.

I think there are also many large opportunities for growth from PoB presented. Extra curse + vulnerability. Good flasks. Twice as much regen from elder belt + doubled life. Potential for doubled armor from gear. Can stack more armor from Grace + Iron Reflexes. Doubled damage from an end game weapon. Panoptician will add a fuck ton of damage. Huge potential boost in tankiness from life as ES + Divine shield. Potential insane STR stacking from LoK league mechanic. Strong unique interactions (Ryslathas Coil, Mantra of Flame+self curse, etc). Phys taken as ele and ele taken as phys is pretty huge. Onslaught on hit. Fully PoB warriored and mirror investment leads to being unkillable / 20+ MDPS.

As an SSF player variety of potential upgrades is exciting.

What am I missing? Tear this build apart.
