Just know that the match order of the All-star game is set by the computer, so i would like to suggest that the All-star's coach should be elected by the eight teams in the same coast. You may ask why? Let me tell all of you some of my ideas.
1. Try to ensure all the coaches will be a human being.....if the final result is more than one users get the highest votes, then who gets the highest marks in the league at that time will become the winner. Or you may ask if some of the users vote for the computer, then, what can we do? Sorry, my answer is you can do nothing on it! If you don't want this case happens on you, try to make the friendship with your competitors ;P
2. More entertaining....I find that all the games played before were also used the same tactics....if it can be set by the human, then it'll become more varied.
3. Build up a communication between the users, if you want to be elected, you need to gather the other users to vote for you. And after you win the election, you also need to collect the All-star players' information so that you can set the most suitable tactic for your team.
I know it isn't perfect enough.....but i think it much better than now, if you have the same desire with me or not, your ideas are also welcomed ;P
