The recently released arcanist has a skill called "Tome-Bearer's Inspiration" that provides a passive bonus while slotted on an ability bar. From my understanding, it provides its passive benefit as long as it's slotted, and not only while it's on the active bar.
If that's the case, can we get a similar treatment for other skills that provide passive benefits while slotted ? Skills such as Magelight from the Mages guild, Inferno from the Dragon Knight or Bound Armor/Armaments from the Sorcerer.
