There is significant neglect when it comes to achievements in the PvP section. It would take just one person actively playing the game to notice that it’s impossible to win Silvershard Mines in under 7 minutes for the Battleground Blitzest achievement. Additionally, Rated BG has been dead ever since Solo Blitz was introduced, which is why wins in Solo Blitz should count toward the Warbound Veteran of the Alliance/Horde – Win 300 Rated Battlegrounds achievement.
This is either an intentional decision designed to keep us playing longer or simply Blizzard’s oversight.
