Honestly. There's more Ads than Zen. You get very little in currency or have to watch ads after every other match. And now to revive all lives is 400 when you only get 10 for 1 match. I am uninstalling. It's frustrating because you will get to a certain point where you HAVE TO USE CURRENCY TO BEAT A MATCH. I've made it to level 510 with no currency to use and failed the match at least 50 times.
