MOST people wanting 2H frost is a gross exaggeration. Only the vocal minority bring up things to "fix" on everyone's behalf. People that enjoy dual wield frost don't often create forum posts raving about how much they enjoy it.
I, myself, prefer 1h weapons on melee classes. But, I also understand that in Blizzard's opinion their vision of the class fantasy for Unholy means a 2H weapon. Oh well. What they believe represents THEIR vision of the class' fantasy and what I believe represent's mine are different. Demanding change based on your assumptions isn't constructive. Even a supposed compromise, for example an aesthetic one in relaxing transmog rules essentially runs contrary to how they view the spec differences. However, I can see them going that route eventually instead of catering to the small % of players that post about ways the way the spec itself to change.
