Thank you for your feedback! In this faction, leveling up and Upgrade both require coins, so just leveling up is usually enough to use up all your actions. This faction also relies heavily on having a large number of cards to recruit warriors. The higher you level up, the fewer warriors you’ll have access to, making it harder to rank up further.
If your Training Area is full and a 3-star warrior gets removed, you will definitely lose that 3-star warrior. That’s actually a critical weakness of the faction—you need to carefully decide which warriors to remove first in order to keep the best 3-star warriors.
Once again, thank you very much!
