Guys, this is not about "how it works in real life".
I do want to see dual-wielding daggers for rogues, though I can see the balance issues as well. Instead of rebalancing "ALL" the weapons and stats and how they and their bonuses work, couldn't they "Only" cut dagger damage in half across the board?
Like it's been already pointed out, there's no need to rebalance any weapons (specifically for dual-wielding purposes). Simply, when you wield two weapons, you get a penalty to accuracy for intance, but you attack faster.
Anyway, is it possible we'll see two weapon fighting in the big September patch?
