I jumped around in Wintergrasp and found a path that brings you under the Wintergrasp Fortress, and inside.
You will also get the achievement - Winning Wintergrasp on 10 min or something like that.
If you are like pretty many running this way you can go outside and kill,
you have to kill the gate before clicking cube though.
Just run to another zone and mount up, or have your character being there before the start.
Watch out for those who joins WG and spawns in the Fortress though.
You need some kind of slow fall, engineering back, mage, Noggenfogger or whatever.
You can do it with flying mount aswell, either get on the mountains to west and mount up in an different zone or take HS to Dalaran, up to you.
How to:
You will see me standing still for some secs, my mouse died lol.
At the last clip I saw that I just flashed the map, but its just above the GY, as the screenshot.
I didnt had any codecs even, so its some shitty quality+advertise but whatever.

I got disappointed when I saw that you have to slay gate before clicking the winzorSadface!
