Would be awesome to see the Worgen be human by day and at night the turn into the actual Worgen beasts.
Picture this, you play as Human during the day doing quests etc. At exactly 9pm Server time All Humans that play this class turn into Worgen form. I can picture several around the mail box at Stormwind when 9pm rolls around then POOF! Howling is heard throughout Stormwind and then the Worgen form takes place.
