Testing it easily confirms its the same as before. Cheap Shot never shut off Auto Attack. However, your attacks never broke the stun. You could keep auto-attacking, the stun would last. As far as I could tell last night, it works the exact same way.
They did reduce it to App 3 for everyone, but I saw no real perceivable change in its behavior. new scouts will no longer waste rares on it. Those of us who did, oh well, at the end of the day it was just a rare, there are more out there, and MMO economics change all the time anyway.
