The game is trash! Ex's are superior/broken in comparison to almost all the characters in the game. Then their drop rates are impossible low. Guaranteed ex's cost 1000's of gems. You can't reach that amount via free to play and the cost of gems/tickets are way too high. Can literally buy a new game for the high end prices that's in bounty get you 1 to 2 summons. 0.200 drop chance is too low. I dropped 800 (earned/free to play) gems got no ex. Also cheaters/hackers run freely.
