Is fire hit based srs necromancer leveling a thing or would you play something else ?

So at some point im wanting to do a full spectre necromancer in HC SSF. However it means i first need a build to get to dread and start farming it for dark monarch and bone meld, maybe even Congregation support before fully swapping over.

The idea is that if you go fire hit based you dont need to farm any of the poison stuff or envy weapon you would for poison srs. You also dont need to get unholy might node so can instead get leech for extra defence.

I would be using anger with genorosity to add loads of flat fire dmg to them then tempest shield and either purity if I need ele res or determ if armour is more needed. Plan to go arm + es bases then using 100% inc armour body mastery to get loads of armour from chest and the extra res if all bases armour mastery.

Plan to gamble for basic life + res gear before maps then first atlas tree will have Jun so I can start working towards katerina bloodline and getting a Bitterpoint shield with +1 spectre unveil.

The idea is then once you get the gear from farming dread you can swap and just use the same jewels, trigger wand instead of a massive swap that you would have to do if you went poison based first.

Then with dark monarch + bonemeld and umbral army i would get 140% inc defence assuming just 10 spectures.
