Seriously, the mindset of people like you baffles me. "Things that have NO direct affect on me, but I don't like, should not be allowed to happen in the game." is something I see far too often on these forums.
The BS patterns - as far as I can tell - are all patterns that were removed from the game when weaponsmithing/armorsmithing was removed from blacksmithing. The weapons, in my and many other people's opinion, look freaking awesome, and its a shame that people wouldn't be allowed to get those models for transmog simply because they didn't happen to have weaponsmithing (and hammersmith for Stormherald, swordsmith for lionheart executioner, etc.) before it was removed from the game. Considering the fact that implementing this probably took very little effort (as the art was already created and in the game), I can't understand why people would be upset with them adding them.
It seems to me that you either simply want attention from people by posting a completely pointless "anti-whatever blizzard has done to wow lately" thread, or you truly cannot stand other people getting something that they will enjoy.
The fact that these weapons, transmogging, etc., etc., are in the game should not detract from your play experience, unless your narrow-minded view of how things must be in WoW is so twisted that you must condemn a large portion of the playerbase - that not only enjoys these things, but vehemently asks Blizzard for them - to playing the game that you, personally, think that WoW should be.
