I was impressed by this game, until recently, when I started to hate it. Even with the best internet connection, and great device, this game keeps crashing, and when connected breaks into the game, you automatically lose that game. That is so frustrating, you could at least put a ping counter on the top, just that we can see is there a problem with our connection or with the server. 
The second thing - game is full of popping up, unnecessary things, that are really ******** and worsening the gameplay so much.
It seems that the quantity of unnecessary features prevailed over the quality of the game, that's really a shame.
