I really feel the game need this soon, since it will add more options to the game. Like dual wand or Dual swords, I think all classes should have the option to dual wield if they want to. I dont find the current options fun I need more options, we have tryed all combinations by now it would be a fresh option wich will allow new thinking of possibilitys.
I could also see a offhand added to the mage and acolyte instead of a shield.
