I guess this was a learning experience for both me and my son and I have deleted the game.
If you want to let your kids play this you would have to be really involved in what they are doing. I have played this game for the last eight monthes. It is common place to see children every few minutes, in the global chat trying to "hook up", or find a boyfriend/girlfriend.
The minimal violence isn't any worse than what kids see in cartoons or Skylanders games.It can be harmless, but parents do not know who their children are interacting with, or even what type of content their children are being exposed to by playing a game with other adults who are strangers.I would just make sure you know that your children are playing this game and that there is the potential for chatting with adults in a clan group chat.I tried to report the abuse but there is no facility to report abusive language in the clan chat rooms.I think this is unbelievable in a game widely played by kids and in my opinion marketed to kids too.
