In my opinion i think dual wield is best not because i get two swords OMG + lol but because with some skill and talent and agro control DW is the best way to deal out a quick death to a mob or mobs. Yes i can take on 4-5 mobs I can hold my own against 3-4 mobs without breaking a sweat. How do i do this? Simple if you use the right skills and the right movements at the right time u can easily keep the mobs under control... heres an example - with dual wield u hit Fast so 99% of the time the mob your attacking wont hit you once.. all u have to do is walk around him and attack avoiding the other mobs but yet making them chase you and you wont get hit or very few times at least also u can run away and run back (its very important that YOU meet THEM because if you wait for them to come to you they can stun lock you because of all the mobs atking you then your really dead) then stun them with a physical aoe hit them a couple times and run away again before they even think of atking you that I call kite smashing its complicated but easy if u have the right skills. Also u can do this with out moving if u have enough aoe skills and time them right.
