This is awesome! I hated it when they introduced T9 and T10 to be buyable with emblems only. The way it was in Naxx/Ulduar was perfect Imo, it actually showed your progress (except for T8,5 gloves which dropped from Mimiron, very hard boss at the release, and from... Emalon, puggable boss)but also allowed you to buy one piece or two if you wanted to save your dkps for something else or didnt want to raid and just get it from farming heroics.
