Not a day goes by when I don't see Alliance grouping up to gank 1 person, or only killing people if they're already fighting something else, or if they get Assassin they will hide in the Alliance base or with 20 of their friends keeping them alive... but then the moment it seems like Horde can actually get a fair fight with them, nope! They'll not engage, or maybe they will just sit on their flying mount high up in the air where they can't be fought since the odds are actually fair. It's quite perplexing.
