Were you always able to hug the wall next to cemetery and attack anyone through terrain? Today was the first time i saw someone doing this. 3 players camped the GV and were able to cast at full range, ignoring the hill in front of them and they were also attackable.
This is more like a cliff and if you stay a few yards away you wont be able to attack due to los, but if you hug it, you will be able to kill people that are way behind the graveyard
