So you're a Hordie runnin the Alliance flag across the field. They're not too happy about you stealing their flag so they send a bunch of gnomes to knee cap you. You're being swarmed by anckle biting gnomes at the base of the tunnel. You need to get away, but you'll never make it all the way up the tunnel.
If you ever find yourself in this situation, follow the steps.
1) Move into position to the right of the tunnel entrance.
2) Hopp onto the small rock and position yourself near the back edge.
3) Press the "W" key and spacebar to jump to the invisible stepping stone.
4) From here, turn your character towards the sharpened log jutting out from the roof and jump to it. (this is the hardest part of the jump, it may take some practice.)
5) Now all you have to do is run up the roof, hop the fence, and cap the flag.
This is not a very well known jump. When I use it, other players try to follow me but fail. They don't even have time to mount up and run up the ramp before the flag is capped.
This jump also gives the horde a slight advantage. I tested this jump with every race (Horde/Alliance) and both genders. I found that I could make the jump flawlessly with almost every horde character, while many of the Alliance races failed. Poor little gnomes lol.
On a side note... when standing on the roof of the tunnel, you are immune to death grip. Also, once you hop the fence, you will be out of LOS of all ranged attacks.
Well that's all for now,
Happy Hunting.
