Cash Grab, Network Disconnects, and More. This game is a obvious grab for cash. Free to play players are limited extremely by this game as it is nearly impossible to get legendary cards unless you buy gems or offers that constantly pop up. Get ready to watch a lot of Ads to progress. Game play has issues with random disconnects. I noticed this seems to happen when placing a unit on the field or upgrading. A solo option would be a great choice if you don't want to play against or with someone.
