There used to be a way to get behind the horde base...blizzard thought they fixed it...they were wrong...on the horde roof you must have
A:friend on opposite side that can fear perferable class warlock
B:being in same bg as your friend
C:standing near logs on horde roof that block you from the outer edge
Steps
1:move and stand next to the logs
2:have your friend fear you and hope you run through and stay there
3:follow path along get behind horde base for either exploring (you can fall through the world or hide flag there and teleport into horde FR if you jump into the wall right over the hole in the floor its obvious once you get back there)
Yes you CAN get banned for this!
I used to go there a lot to hold flags for my side but using a differant entry point which has been nerfed =/ try it out I am 99.9% sure it will work as I have feared people through the logs on accident in 1.13 and am highly sure it works after the recent patch
