I think you're forgetting static. Two quick room-wide convicted statics will drop any immune to 39% of their health with the self infi build, or 46% health with 3 casts of 200 fcr build. 60k health light immunes drop in under 2 seconds, including the time it takes to cast the statics. The rare 900k health light immune herald takes 19 sec for self infi build to drop, or 28 sec for 200 fcr eschuta nova. I know fire sorc is much faster for the heralds but for most tanky light immune mobs, the self infi nova build will kill drop them before the fire sorc can cast all 6 hydras. For fire immunes, the disparity only widens.
Believe me I love fire/hydra and might run it next ladder though. It's a really fun build.
Still an issue of being forced into short range vs heralds and reliant on tagging 15 creatures with conviction, especially with eschutas where the difference vs immunes is 31% more damage (with -93% on a fire sorc, conviction is 17% more), so you lose quite a bit when the merc dies. I don't doubt nova chews through non-immune non-herald non-boss creatures much faster, though even champions/uniques static doesn't quite make up for that difference in kill speed. Because fireball doesn't even bother with static even though it has it and conviction, when its just pew pew kill them in a few casts. At the end of the day, eschutas nova deals 6k damage per cast with -50% pierce, fireball can be 17.3k damage per cast with -93% pierce.
Not even looking at the tankiest like venom lords with their 200% hp scaling, some 100% hp unique+minion mobs will have 67k unique / 50k minions. If not immune, fireball kills them in 2-3 casts, nova takes 5-6. For the immunes, where sure fire is more plentiful than lightning, fireball still only takes 3-4 casts, but nova takes 15-16 without static, maybe you cut them to 50% hp in 3 casts so its 11 casts. And again that's for mobs like steel scarabs (~95% hp) not big tanky venom lords. Let alone the truly tanky bosses and heralds where fire sorc gets to deploy the shinra mako cannon with hydras+meteor
