These tests are good thing. But i feel that there's only one way to figure out the best tactics. Is to make championthip where every team is exactly the same as the others. Better if every player will be with all 20 attributes so that there wouldn't be a better attributes that suits more for the exact tactics. Plus the same max attributes for managers and assmans. Even field dimentions must be the same for every stadium. And i believe than even the attendence does matter. So the attendence must be somewhere qual for every team.
I guess this is the only way to figure out best tactics. And i believe that different tactics is best for different field dimentions. So better to simulate few championships with different field dimentions.
But i don't think that there's any meaning to make such test with this years FM. It will take to much time to create such league. But if you, Will, somewhat agree with me. Take that message into account when FM16 will be released.
