I beg for this. I found the Jedi Battlelord set on Torhead, and then later got every piece from the GTN, except the belt, at around level 30. At level 50 I stormed the final area, repping my great Jedi Gear, but the experience, I feel, could have been much greater if I was able to put the hood down on the gear. Jedi are not ment to be afraid to show their faces. I think it'd be more appropriate for Sith to be the ones wearing the hood with a mask etc.
Oh and by the way, the hood down toggle couldn't be too difficult. I just did The False Emperor and the final boss, whom I won't reveal for spoiler senses, actually took his hood off in an animaton. It can't be too hard to preform it since I'd assume the hoods in the game are uniform, as in the same hood model was used for all the hoods existing in the game.
Please Bioware, give us some indication you are working on it, or making some kind of progress towards helping us bald Jedi Knights!
