When you are custodians of the world’s most popular multiplayer shooter, you need to ensure that there are no balance glitches or errors that disrupt the game. Otherwise, some players get an unfair advantage, and the entire metagame comes crashing down.
Of course, Blizzard are excellent at responding to problems like these, and at keeping older games alive with post launch support and updates, so this shouldn’t be an issue for very long. But for now, I guess, avoid playing on the Antarctica map at all.
