When trying to train new/weaker dragons, continuously having to change the setup can be frustrating. It would be convenient to have a setting where you can choose which dragons are your preferred choice for a March, not just the strongest.
Like a way to "favorite" your dragons and have them show up first? I like it. I would give this idea a golden star. Though we are still waiting on a lot of improvements in this aspect, such as pre-set marches or a button to send a min-hit march. :/ ATA is just falling behind on these great ideas.
