Ok, aside from that failed pun, Blizzard (or Ghostcrawler himself) decides to get rid of head enchants in MoP. They just don't like the idea of being stuck with a faction you didn't like because it had what you need. Not to mention there was more factions in the upcoming expansion this time around. There were more reasons as to why they decide to get rid of this option, even though its not the perfect solution. Some players mention that it could be used into professions, such as Engineering or Enchanting. This idea could make professions a little more worthwhile when it comes to the auction house. He should probably take a second look upon the matter.
Nevertheless, it is a design choice that seems reasonable enough to let go and something I wouldn't mind either.
