PoE 3.20 Sanctum Pathfinder, Spell builds

So this has been a fun build to put together and I've spent most of my currency this league on it, but I don't feel like the DPS is where I want to be. I'm sitting on 40% CDR and 146% cast speed on my temp chains. If I add the 990% cast speed to bring the PoB cast speed up to the CD value, I'm sitting at 1.8 mill dps. This seems fine for normal mapping, but about 10m short of what I would like to have for bosses.. &x200B; Are there any straight forward upgrades to this build dps? More CDR from boots, or possibly belt? I'm farming sanctum for more relics, but they are just such tras

I chose Fireball over Creeping Frost/Ice spe

Has anyone tried something like this? Expedition's end would guarantee huge freezes. Either Annihilating Light or Crest of Desire (maybe both for double herald?) Could see it working on either raider or Pathfinder. Raider gets speed and elemental synergy. Pathfinder could get speed and possibly a boatload of crit from flasks. Going to try some
