Light Stun fix did nothing

I was quite excited about the light stun fix that made it into the patch yesterday, but that excitment quickly turned to frustration and rage.

Playing a Bloodmage bonestorm/dd build with points invested into stun threshhold. I still get light stun locked from the same white mobs off in a corner hitting me with basic attacks. So to me it feels like this attempt to address light stuns being a problem did absolutely nothing.

It's so very frustrating to deal with because I get interrupted out of casts. Those same casts are an attempt to kill said white mobs off in a corner.
