PoE builds similar to [3.19] Firestorm Inquisitor - 10k+ HP, 4k+ Regen & 4.6 Mil DPS - Just Tank It

Hi, i'm a off meta player and usually like to make my own builds, and i've stumbled into a fun interaction betweeen these skills and intensify, considering it snapshots the damage on the duration of both, i can do a good amount of damage with high intensify uptime, using both on a single 6L. Other than gem setup (i know it's kinda jank, i intend to swap into a staff setup sometime soon), what would be an obvious improvement here?

Got to maps a few hours ago and its pretty ok. Visually S+. Nothing better than dropping meteors on stuff. It just locks you in place while casting which killed me a few times. Just didn´t get it to work with an ignite or intensity build.

No Flasks, no uniques or special items, nothing ticked in config and the gems aren't filled out yet. It already has around 500k dps without using a second curse (allocated points in WoD just for reference) and without the vaal version. To me this seems pretty great but I have no clue if its actually playable. I am not set on hiero, just used it because I wanted to see what impact arcane surge
