Before Summer Update 2008 most Mages used to wear this because of it's incomparable weight/armor ratio. Now it may be better to use a Spirit Cloak or Focus Cape because they provide an extra Magic Level, although Spirit Cloaks are heavier and have less defense and Focus Capes have less defense but is still lighter than a Blue Robe. In the Test Server time, Blue Robe used to add an extra Magic Level, however the convenience was removed after the Test Server. Many people used to believe that these robes increased magic damages by 25%, however this rumour was fake.
