Unfortunately, we realize this will lead to defeats and a loss of trophies, but upgrading dragons is a crucial part of the game. For us, long-term balance is far more important than temporary advantages. We would like to remind you that the first season is a test phase for the game. As a bonus, we have significantly increased the gold awarded for a defeat to help you continue progressing in the game, despite the tougher battles. Thank you for your understanding!
