I do know what you are talking about. To douse the Wickerman of the Alliance, you just have go to the gates of Stormwind, get behind the Wickerman, and put him out. I died so many times (lvl 61) trying to put out the Horde Wickerman, which is inside the walls of Undercity. It wasn't the players. It was the guards!

If there is an advantage for Horde players, I have never noticed or had any problems with getting Holiday achievements.
There aren't even any guards out in the front courtyard of Undercity. I don't really see an issue. It's as easy to get to as the front gate of Stormwind or Ironforge.
Maybe Blizzard are trying to improve the World Pvp you know :P
