Wait til 42-43, i used to aggro the first pack of the mobs to get into the graveyard at that level, once i got level 43 it was easy as hell.
You can also loot the chest inside the instance, it a bit tricky but you can manage to do it without pulling the 4 mobs near the chest, there is also another chest that can be obtain rather easily, but you gotta find that one ;
