i remember many of the dungeons working 3 years back. and now suddenly Zul faral and other dungeons don't work anymore. pretty much from 40-70 there is not one dungeon. also, the last 'working' dungeon is mauradon. and that thing is declared ~38. well, you go in there and the monsters are lvl 45. that's the level they had pre cata. however, their loottable is new. so they drop lvl 32 stuff.
but at least you can go in there. deadmines are declared as working here. but you can actually just kill the first 2 bosses and than there is a door that won't open.
actually, i don't understand why so many dungeons that once were open are not open anymore. i doubt they changed the BC dungeons for example
