Thank you for responding. I ended up getting a lot of Kutas since I wrote this so I did test this out. While I believe the shared cooldown is still a 'Feature', infused in both hands with the same enchant does not affect the cooldowns beneficially.It is a waste to use same enchant while dual wield. For PvP I like to use crushing and disease. For PvE I use crushing and damage. Also, afaik infused on off hand proc slower than on main hand. Would be nice if someone could confirm that.
Here is something that might be a bit old.
