Does Rapid Shot knockback even work?

When I'm using Rapid Shot, none of the enemies are knocked back in any way, not even the smallest ones. They keep running towards me unaffected.

Granted, I've not skilled knockback on the tree, but to me it seems it doesn't work at all so even if I had picked that extra 36% knockback distance, I don't see how that could make a difference.

Anyone has the same experience?

I am experiencing this as well

Tested without any support gems or auras to the same result

Still doesn't knock back with a mostly naked character either

Have not tested changing passive try around yet

i've also tried while using the "clear space" node with no change. Did not work

I haven't tried eliminating all sources of pierce yet but it might just be easier to make a new character to test on

I used it with a fairly new character and the projectiles definitely didn't pierce, so no, that can't be it.

It simply does not work, because I know how it's supposed to look from my sorceress when I add knockback support to the spells.
