This is just a compliment!
I believe you have achieved the perfect balance with Arblaster, Froster, and Pyromancer!
Before you added the two new levels to the Froster and Pyromancer, the Arblaster was imbalanced. And he was really the only useful ranged anti-unit unit.
I had one slot that was always only used for the Arblaster. Now, I’m always rotating them in and out depending on the enemy I’m facing.
Thanks so much! I’m so much happier with the game play and diversity now!
