I don't quite understand what the imperfection of the legislation is?
The fact that playing without control against an opponent with control is extremely difficult has been a known fact for a long time.
The imperfection is that 3 Dimension Door are banned, and you can't catch up without full control. But first, you have to find it. This is what people start taking advantage of, building their game around avoiding direct contact.
But if they knew that in a chase the opponent would use, for example, 4 Dimension Door and still catch up no matter how much you hide, the games would follow a slightly different scenario.
As it is, heroes are gradually shifting into a one-sided quest - find full control
