[3.29] Lightning SRS Luminary: A "failed" build

PoB: https://pobb.in/iThTLgejRio5 (not configured) Some expensive pieces, but also half finished character. Could definitely be better with more effort, but I didn't like the build for a few reasons.

The general concept of Merc aura support seems decent for attack minions, both with or without doryani, but SRS of Enormity didn't work well in the build.

Some thoughts:

1. Very slow cast time feels bad to map with.
2. Too much opportunity cost in increasing the max SRS count.
3. No smite due to wand.
4. Annihilation support with guaranteed crits felt worse than expected, more of a sidegrade to splash. In juiced high density content it might perform better.
5. Needs unleash and annihilation and/or splash for clear.
6. Bad defences but mostly because poorly built/unfinished.
7. Merc aura sometimes has downtime when SRS goes one way and merc the opposite direction.
