It's not that it's hard, it's that it's a reward from an event, and making event rewards available outside of the event for those who never participated in said event sort of invalidates the event itself. Not that it was hard to get the hairstyle, you just needed to complete the first quest of the event. That said, new players join ever week so beyond relaunching the event these players will never get the hairstyle, or even the rest of the event rewards for that matter. Besides, it's just one hairstyle per gender so it's not like you lose out on an entire library of hair... like we presently do now. Why is it so hard to have all the hair be uni-race/uni-sex? I don't get it.
