well I guess bullying in game is ok being farmed to get rid of player in my empire seems a little off. but ok I am rather po deca has blocked me from getting help. Fascinating really was going to spend money on game but I'm rethinking that. however the liars and bullys run the game I think so I now I just heal so they can attack me more all day every day and no help to the little acc. no problem maybe after my losses exceed my attacks they may or may not stop.

I've been playing this game for years, it seems I always come back for more. That changed after this last server outage my character class was reset from assassin to enforcer, but only for clan battles. There's no way to reset it, and no way in the app to contact customer support, so I'm done playing. Thanks for all the good years, good luck on whatever issues you're struggling with.
