So, trying to get a second clear of Alysrazor last night when our enhancement shaman exclaimed something... "This hill wasn't here."
And he's right. Towards the south east where the second Initiate spawns is a MASSIVE CLIFF. Exactly opposite is another hump (though slightly smaller) that can actually LoS you if you hop behind it. Please say we're not the only ones who noticed this and that we're not going insane.
