Hi! Thank you for the feedback! I will communicate your suggestion to the game designers
Suggestion: add some free 10X Champion space box to Arena Gold and Plat and tag team arena Gold reward, increase the current space from 300 to 1000, so more people will fight in the arena for top rewards, in order to be in Gold 4 and Plat, they need better champs and better artifact, that means more revenue for Plarium.
