I just installed the 10.3 updates and so far the things I have noticed and like are:
In the dragon info screen the battle info has been separated into its own tab. With the added bonus of now telling you if you have a trained attack or not. You can also select the train option directly from here. I hope this means that they will eventually let you store or sell your training building to free up more space.
In the empowering screen like the training option you can now select the option to empower directly from the info screen.
You also see the empowerment level and stars without having to select one of the info tabs.
And finally you can now see what the strength of the dragon would be if it was fully ranked and empowered. Though I could be wrong about this because the numbers do not seem to be right.
You also have a button to take you to the battle options in order to rank up your dragon from the level up tab.
Things I do not like, I am not sure but I think this update is not 100% because it is showing several heroics as not being trained when I know all my heroics except Scorchwing are trained.
Also it would be nice if they had an option to take you to it in the dragonarium as it does when it takes you to the habitat. These are some nice improvements.
Are there any other improvements that I am missing?
