In the new build of the PTR 10.0.7, Blizzard has decided to make it easier to manage the talents of the dragon flight. Now, all you have to do is right-click on a talent to unlearn it and recover the points for the corresponding dracoglyphs.
Additionally, confirmation windows have been disabled, making it easy to activate and deactivate talents. In absolute terms, it’s not very useful at the moment. However, with the arrival of the new talents of patch 10.0.7, then the talent of patch 10.1 (allowing you to recharge your Stamina when you fly close to the ground), you will be able to “play” more easily with your talents.
It’s an improvement that won’t change your habits but will make the interface more practical.
