Really agree, making them dual wield in the traditional sense or just don't both including them because its nothing more than a gimmick. Whats so difficulty about balancing them for 2x 1h weapons compared to 2x 1h swords or any other melee weapon.
Perhaps it was just a stop-gap to get them in for blizz-con as I really can't see the reason to implement them in their current form. All we're basically getting is another 2hander with a different model and animation.
