New Pet Skill Known Issues
The tooltips of the recently added pet Master type skills incorrectly state they are Passive skills, but they are cast on the pet's master while the pet is in combat, they are not passive skills.
The skill type in the tooltip of already learned pet skills is also incorrectly showing "Racial Passive" instead of "Active" for all non-passive skills.
Both of these tooltip bugs will be fixed in the few days.
