there will never be a region lock. The only time this happens is when the 'man' , in the country you reside, does not allow the game to be played. As I mentioned above, gaming vpns get around any region lock. Even if a game did get region locked, only a fraction of the player base would be affected. Why? Cause they're cheap and easy to use. If I play on the NA server, the highest my ping would be is maybe 150 and no packet loss.
