I thought wall jumping was taken out at the end of BC. But recently I was exploring BWL and came across this large hill and I easily preformed at least 10 jumps in succession and reached the top. Does the fix not apply in some dungeons/raids or did the WoD release screw this up in addition to some other exploit elements? (no fog, visible invisible walls in BGs etc)
