The other week, I was in Blade’s Edge Mountains with my Paladin doing a quest chain to pick up a chestpiece that, in addition to being an item I want for Transmogrification in the long term, is also an upgrade now because she’s not using heirlooms. Rexxar sent me out to bang a drum for the marmots, and I realized that if this quest had been written in Wrath or later, it would have launched a vehicle UI instead of simply replacing my character’s action bar.
In old Thousand Needles (vanilla WoW), there was a Horde quest to use a robot to steal some water from the moonwell in Thalanaar. I’m not quite sure anymore whether the robot control console replaced my character’s action bar or gave me a pet action bar for the robot. However it was done originally, this quest would probably use a vehicle UI if it were being written in modern WoW.
Do you remember any other quests from BC or Vanilla that would have used the vehicle UI if they’d been written in Wrath or later?
