Hey all, been a while since I OP'ed here.
Shadowstep rogues only.
But anyways I hope this is helpful and useful to anyone, in AV you can run to the Frostwolf village outside Drek's room, and ShS one of the guards on top of the tower.
Im seeing this as an exploit as because I guess Blizz didnt intend for us to have an insta-lift to the top of the tower.
Anyway, this space of seconds rather than running up the tower actually got us the advantage, we downed Drek whilst Vandar was on 2%.
So to recap.
1. Be a ShS rogue, and run to FW.
2. Make sure there is a bowman on top of 1 tower.
3. Shadowstep him/her, which makes for an insta-lift to the top.
4. Beat the horde marginally.
I hope this was useful to anyone, and I tried to give it a structured layout.
Thanks for your time.
