We have an obligation to players and to our hard working artists to keep the game from looking too silly. ...
The idea that Blizzard wants to reduce silliness in their games -- even more, that they feel they have an obligation to do so -- is kind of funny. WoW doesn't have a fourth wall. It has a fourth highway.
Yeah, there's really no defending that comment. Just to review, here's the non-silly items we're saying you can continue to wear:
http://www.wowhead.com/itemset=218 - blades everywhere. Running will actually kill you.
http://www.wowhead.com/item=21391 - the insane clown shoulders
http://www.wowhead.com/item=21615 - pimp hats
http://www.wowhead.com/item=11839 - you can make your uber-protective helm look like a monocle
http://www.wowhead.com/item=15272/razor-axe - a giant razor blade
But we don't want you to be silly... no, silly would be bad. :-/
