Haven’t played in months, with the changes to FHR, is FRW on casters still important or did the auto WSG kind of negate the need to stack it as much?

Depends on matchup.

But generally speaking, yes frw is still needed

good fhr and high frw can help u run out tight apots especially against ww barbs

Still need frw for avoid being stomped or quickly running out of skills' AoE
