I was really surprised after playing the beta to not have this option available to us. Most if not all of the MMO's as of recently have this option in order to better customize your character. Of course this is a much different type of MMO, it still would be nice to atleast have the option. I realize that in the tower your helmet is not showing, but it is unfortunate that the player does not get to decide when it shows/doesn't show. I can imagine that there are people out there who would rather show their helmet in the tower as well. Either way it's about being able to have the [i]option[/i] available. If you have any thoughts on the topic, or would also like to see this feature become available, post here for a discussion.
I don't know what to tell you. I wish it was there. Bungie is sorta a nope outfit. Really cool ideas saddled with all this great potential, but ultimately they just never really go that extra mile on things you'd think would be fun to do, or have as an option over whatever it is they thought was good enough.
