My complaint:

I’m tired of wasting gems and still this game is to hard. I’m not spending another dime and will delete this if some changes or something is not done to help. I want to have fun not feel cheated by this game and feel like you get no where and have no chance to win. All I frigging win are feathers or black pearls. The new arena sucks

Suggested solution:

Make it fairer and a chance to win better n give better prizes than stinking feathers n black pearls
