Seriously, In the last 4-5 days I frequently logged in the test server to try the Battlegrounds. I play at very odd hours throughout a whole day so I’m sure that what I saw was a constant situation and not something temporary or occasional.
Between around 30-35 attempts only once I was able to find a working Battleground. All the other attempts were in a broken BG due to missing flags.
Of course this is just one of the many problems and exploits currently in the game but for sure it is enough to break the whole thing.
As far as I know nothing at all changed these days. So again:
What exactly is Blizzard showing at the E3?
