Blocking the Heroes & Generals client from matchmaking to certain regions can have certain benefits, such as not getting into high ping matches.
Note that this guide only effects matchmaking and will still allow you to join a friends game in that region or squad with a friend of that region.
Note also that doing this can impact queue times if you block some regions. The more regions you block out, the more likely it will be that your queue times will be longer. If it does impact queue times you can always disable the rules in the future.
