The Diablo 3 designer John Yang made a further explanation on the official forum about the adjustment of 2-Handed weapons. He responds the questions why the 2-Handed Crossbows/Bow are not changed, and why they don’t add some extra stat rolls and sockets to the 2-Handed weapons. And the main reason is to avoid more critical hit damage. Here is the original post:

"Currently, 2-Handed Crossbows/Bows are very competitive with 1-Handed Crossbows because Demon Hunters can use a quiver with any bow type and as a result, 2-Handed Crossbows/Bows do not require a rebalance.

Increasing the stat rolls on 2-Handed weapons so they are equal to two stat rolls of a 1-Handed weapon is a common suggestion and one we’ve definitely considered. Unfortunately, this solution would have the undesirable consequence of enabling only one class – Crusaders – to have the highest possible amount of certain stats from gear (e.g. Cooldown Reduction) when using both a 2-Hander and a Shield.

Adding an extra socket to a 2-Hander effectively translates into more DPS. Yes, we could do that, but as some players have begun to point out, Critical Hit Damage is a problematic stat for us. Because it multiplies with Critical Hit Chance, it causes both of those stats to feel overly mandatory. We would much rather further increase 2-Hander base damage than give out more Critical Hit Damage.

To give an extreme example for this topic, if we increased the base damage of 2-Handers by 10x, 2-Handers would definitely not need an extra socket or higher stat rolls in order to be competitive. That example tells us that we can continue making the distinction that 2-Handers hit harder and make more efficient use of resources while 1-Handers generate more procs and have more of certain stats, and not have to settle for a solution that unfairly gives a higher cap of certain stats to Crusaders or exacerbates the issue with Critical Hit Damage.

The current 2-Hander buff is a safe first approach. We don’t want to swing the pendulum in the other direction and make 2-Handers the only option, so we are moving carefully."
