Vanilla BWL and MC

This might not be an appropriate topic for this forum section but since it is about raids and dungeons it might just be! Currently, on Neltharion, BWL and MC ( Blackwing Lair and Molten Core) do not work. MC doesn't have mobs and I didn't try to enter BWL but they told me it does not work either. There are some quite good transmog items in there such as t2 class specific gear or for example t1 in MC. Alot of people would actually enter those raids to get those pieces or just for fun or in general the mobs over there drop materials for low level proffesion plans, patterns, etc. My question is when and if they are going to be fixed and put in to the game as intended. Thank you in advance for all your answers!
