For me 2H > 2 x 1H in PvP

With Dual Wield you make more auto Hits and more Auto Hit Damage, 2H is more Style Damage -_-

i have both weapons but i hate me that i buyed the one handed weapons -_-

For a Boxer i think is 2h the best way but i play it with mastery because haste is great but only for runegeneration its too low as Boxer (autohits dont matter as boxer )
