Might be a dumb question, but I think it's an important one to have verified... all of the current gear on Mangler with focus effects disabled, such as the Obulus Death Shroud, will switch to enabled with Luclin's release on the 20th, right? They won't stay disabled and only items dropped after Luclin's release be enabled?
Correct. According to the original FAQ for Mangler, focus effects will unlock when Luclin goes active.
