Knockback is garbage

Ok guys. But can you share a good knockback build ? Cause i go directly to the King of The Hill skills + some more CSC skills and i'm still have only 10-13% CSC on my character sheet (with a 5.95% CSC on bow). In game, it's mean that i see only a really few mobs being knocking back (ok, the most of them are often one-shoot killed, but not all of them).

So for now, i have to say that i'm a bit disapointed by this skill. Or hoping i don't get the right build.

Edit : I'm thinking : perhaps i simply have to get a better bow :D :D

Oh yes, i forgot to precise that i'm looking for a knockback build for a ranger bow class

knockback is good with items like Chin Sol it works with rolling golems they dont hit you most of the time


other annoying enemies like oak can be keep at bay

Knockback should knock the mobs further back then now. It would be cool if a fully synergized and supported knockback attack would just knock a mob straight out of the POE window onto an Excel spreadsheet or onto my browser. Even knocking them onto my desktop would be kinda sweet.

Also, where is the "faceroll" button for this game?
