How about a mini event that rewards mastering certain in-game skills.
There’s been a lot of emphasis recently on the forums about rewarding good flying and an event like this, even as a one-off might help achieve that. I appreciate it will be significantly easier for some than others.
I don’t know exactly how this would would work and whether players could, within the event, have access to dragons not in their roster but things like taking out high level perches on the turn using Ember, sanding/vining an entire base, blinking etc.
Feel free to add skills you feel would be helpful for the dragon flying community to learn.
