Yes I believe the skill nullifier always worked like this, BUT now skill unleashers can target it while the nullify skill is not "on standby". it's good skill unleashers can't repeatedly proc on the card, but it's quite a strange behavior altogether. however, i'm pretty sure this is going to be the key to doing significantly more damage to the new Legendary AW.
