sorry for the giant pictures
to start you dont use a way point.. run out the arreat gate into the battle fields and this is the map your going to look for
This is where you want the mobs to be. sometimes there will be some there.. but the best way to do it is to kite the mobs there.. die then run back to the top of the platform
This is where i will typically kite them before i die
