oy, what's this fascination with dual wielding? If you want to dual wield plate wearer, there's already a class for that called the warrior.
If you want to dual wield 1 handers and do small amounts of damage but at a very rapid rate, there's a class for that as well called rogues.
If you want to dual wield 1 handers and do small amounts of physical damage but have spells that hit for larger amounts, there's a class for that too called death knights.
If you want to dual wield 1 handers and do huge amounts of physical damage coupled with instant spells and drop sticks on the ground, there's a class for that too called shamans.
If you didn't want to hold a huge 2 hand axe/mace/sword and be able to hit crap REALLY hard slowly, why the hell did you roll a ret paladin in the first place?
