The first account was blocked after 5-6 days. I created a second account and have been playing for 24 days. My conclusion: Wherever there is a rating of players (arena, events), it is forbidden to take places above 250. The optimal place in the rating is 350-250. To kill the guild boss and defend the victory: In the menu, set damage + defense 999999999, but do not beat the boss (he dies himself) and protects you the victory, if you touch the boss, there will be a mistake and you will not protect him.
