2.The opponent who is online and who is in your chat list close to you - this enemy will choose you the system if you will come to the arena
3. And as soon as the enemy disappeared from the chat, then he went into the arena at this time need the same to enter the arena with a probability of 99% you will fight against him!!
Please tacticsoft make the system of selecting the enemy in the arena more difficult, it is predictable… In your system, there is no random selection, your system of selecting the enemy to deceive!!!
