This is one of my biggest qualms with Blizzard. WSG wargames were recently enabled - they told no one, and only addressed it in a forum post after it was discovered.
Around the same time, WSG in retail added a feature and it was front page on the launcher.
Also, why did they ever split the battle groups? Time zone? The real answer is still unknown to me. Either way, this chocolate cake is way to salty.
