I don't think limited events should be brought back all the time because people say so. That kinda defeats the purpose. It certainly won't hurt me, but it doesn't make much sense either. The Lightning and the Shantotto event were brought back eventually in last August for the one year anniversary event that was heald as a thank you for players. That's when I did them both. It is not impossible that we will get a second year anniversary event as well. However I don't think SE will or even should bring back a limited event just because people don't like the current hairstyles.
