In my opinion, there is a lot of nice weapons that look cool: trollbane, captain's axe, lightning and vorpal swords, heartseekers and lifethief, flamestrike, charward rods, etc. If devs make them as vanity, it will be great, because big and fiery trollbane looks much more beautiful than dull and white storm sword. In addition, some weapons look great if worn with a certain vanity set, for example, purple founder looks great with lightning sword or trollbane, as same as gold ranger with heartseekers or lifethief and founder mage's set with nordr jewel.
