Percentage-to-percentage nerf of roughly -33% to -40%, depending on the roll.
Thicket of Blinding Light’s damage and blinding effect now has a maximum range of 8 meters (from 12). Its damage is now based on distance, scaling linearly from 10% at 8 meters up to 100% at 4 meters away.

Estimated overall build change:
About a 30% to 50% damage nerf overall, even before factoring in the range/falloff change.
G U T T E D! 
Maybe this build could have used a little balancing but instead, in typical ARPG balancing fashion, the devs used an overly heavy hand and completely wrecked it, destroying everything that made it fun.
I guess I’ll keep playing Path of Exile, and try out the new Blade Vortex Minion Pact build, or stick with a Righteous Fire build for this type of build play-style.
On the bright side, the $90 I spent on a PoE supporter pack feels more worthwhile now, and it saved me from spending more money on supporter packs here.
Maybe Season 5 will look better… a year from now.
(I posted this in the patch note thread but think its better in the Primalist section)
