Wall walking is back in action for a while but difficult to do.
There is a macro for this.
Go to the macro option, and make a new macro copy/paste this into the field.
---Macro---(dont copy this)
/run local p,f,m,t=Minimap,CreateFrame"Frame"m,t=({p:GetChildren()})[49],p:CreateFontString(0,0,"SystemFont")t:SetPoint("TOP",0,-9)f:SetScript("OnUpdate",function()p=m:GetFacing()/PI%.5;t:SetText(format("\124cff%02xbb00%.3f",255*(1-abs(4*p-1)^92),p))end)
---End Macro ---- (dont copy this)
make a button on your actionbar with the macro now click on it, if you did everything correct you get numbers on your minimap.
Stand against the wall (straight one) you wanna walk on. stand at the point that the numbers turn green.
These numbers differ between 0.497 and 0.003.
Enjoy !
