Hi, unless this wasn't labeled as a strand of the ancients exploit before (yes, I did a search), this one is new.
First, you have to be a feral druid because you'll need feral charge for this.
The basic idea is to use feral charge (cat) to get behind a turret and, therefore, get behind a gate early.
To get this to work, you must be
a) in the line of sight of a player upstairs or the turret itself
b) quite close to a hill or similar
With a bit of luck you'll jump up to the legde. If it doesn't work, try the other turret.
Since I'm still a bit lost at strand of the ancients I can't tell you which gates work and which don't (however, I did it on at least two). I'm yet uncertain wether the hill or the height does the trick.
Also, I'm sorry for the lack of screenshots (I don't really think you'll need them anyway). Still, I might add some tomorrow.
