v1.7.0 Update
In case you hadn't noticed yet, the website now has a team builder!
The team builder will suggest you characters based on the team leader and the rest of the selected characters. It'll also recommend the best leader to use for a select group of characters. I do think I did quite the better job than Dokkan Battle's built-in team builder!
Signed in users can save their team, this will create a permanent link to the team to share on other media outlets.
The team builder is still in beta, so you might encounter bugs or miss functionality. Don't worry, it's in active development. If you have any feedback, make sure to share it in the Discord server.
