[PoE 3.23] "Mid budget" armour stacker scion showcase

Apparently 4-5 mirrors is "mid budget" now, but this is where I dumped all my currency so it is a shame not to make a showcase even though the build isnt original. It can use any projectile attack skill with a sword, I swap between Lightning Strike of Arcing for clear and Molten Strike for single target.

3M armour with 6% of armour applying to elemental damage lets us facetank uber exarch's balls phase. Very satisfying because I always die to it normally. The barrage attack is dangerous because the build has 4k ES regen but no es gain on block or anything of the like, and of course I die sometimes to the lantern blast at point blank range even with molten shell on.

Is this build strong? Absolutely probably the strongest build I've played so far by a long shot. Is it worth the money? Probably not... I could have made 5-6 other builds in the currency I threw into this one.
