Dont know if this has been posted before but u can duel wield as a paladin all u have to do is equiped a two hander like Whirlwind Sword any two hander will work and then get a wepon that is for offhand now right click(or drag it) it and it should be equiped in ur offhand now just get a main hand or 1 hand and drag it to ur other hand.... there ur a duelwielding paly(sry for bad spelling)
even thoe the offhand is red i still did it on my server and on mine it does do damage specialy with the thing that does holy damage when u hiot it do like 1000 fast.....
