There is one major problem with the exporting of WoW models from the recent 1.11 patch. Because anyone who plays WoW downloaded the patch in seperate pieces, it is impossible to get any model out of that patch because the models are in pieces (not one model, but the .m2 is in 3 or 4 seperate locations). Because of this it is very very hard to export the Kel'Thuzad or any model from the 1.11 patch. It is probably possible, but will take even more time than exporting a character model.
