PoE Raise Zombie, League Starter, SSF, Fire builds

So we all know good old SRS. You have 20 of the little buggers, they swarm around headbanging things and living out their short blissful lives. Sometimes they even go out with a bang, and the sound of 20 skulls exploding multiple times a second is the good old SRS Popcorn. But what if the explosions were bigger? MUCH bigger? (tl;dr: 3.8 million current damage per SRS pop, could get up to 22mill under absurd conditions; pob: clips: mapping: harvest: and drox: http

Here's a quick update to Kay's popcorn SRS build I'm considering for SSF league start this Friday. I've tweaked a few things, increased some defenses. Have a SSF starter gear set and bare bones tree and damage looks decent. Any thoughts? I'll need to tweak the build more once PoB updates with new craft bases and gem modifications.
