Fire Shockwave Totem (70% phys as extra fire)

I can get someone to help me with my Fire Shockwave Totem build?

So the weapon/shield has 35% phys as extra fire while cast linked to searing bond totem (70% extra).

Skin of the lords, +2 wand, +1 shield, +2 amulet gets me lvl 33 shockwave totem. I could eek out another level with lvl 4 empower or two with awakened. With my setup I have max 1 searing + 6 shockwave totems. with all totems up, tooltip dps shows 250k per totem so about 1.5m? I'm sure it's a little higher if I could properly check on pob. I honestly had higher hopes with the gear.

There are some gems that still need leveling, flasks, annointing whispers of doom, and stuff, but not sure what the best way to scale would be. Currently sitting at about 55% crit chance, 333% mult so that's one potential avenue? Should I try to scale aura effect for herald of purity? Should I just drop all defenses (should i drop suppression?) for damage helm, glove, boots? Should I find a crucible unique helm for another 35% phys as extra fire? Should I drop my passives for totem/crit cluster jewels instead? any gear upgrade suggestions? any +1 all corrupted chest worth replacing the skin with?

I was hoping this would be a good bosser, but feels kinda shit unless I can scale it to do far more damage. Totem health is shit so bosses keep wiping them out which kills dps and sometimes the synergy. Searing Bond totem also has a shorter duration than shockwave totem, fucking up the rotation, and making it awkwardly replace totems because it needs to be cast with multiple totem support or I lose 1 max totems. The clunkyness could be okay if the damage was better though. If I never need to searing bond to map at all that would be nice
