Nobody is really interested in this PvP Arena, the mechanics of if is not correct, the reward are fuzzy, Considering only the top 10 players will win something why not suppress this PvP Arena and simply directly give the prizes to the top 10 against diamonds, as we all know that this is only done to make them disburse diamons.
On the other with the PvP Towers, everyone in each vicinity was pleased to win someting against his neighbours.
Then you exchanged the joy of hundreds of players against only the top 10 for some dollars in your pocket.
Down the road the game is dead as without joy people are leaving the game by hundreds.
Shame ! Shame ! Shame !
