Allowing 12 foreign players is right?

There is rumors that the Tanzania Football Federation may make changes to the rules to increase the number of foreign players who can be registered from 10 to 12

However, the rule will come with a condition that no more than eight players will be allowed to start in a major league game

There has been an online debate over the changes as to whether they will be implemented and their impact on our local players

Is the increase fair or will it have an impact on the future of local players? and possibly affect the National team?
