I was all set to go DW/2h with this 2.4 patch, instead of 2h/bow. However as I was building it I find I end up really only needing Rally ability out of the 2h abilities. Now this is just for leveling so I am not running any potions, but even without Rally I believe I can get better performance with going dw/bow. I can use the 2 bow dots instead of having the Brutality buff, and use Bloodthirst for my heal.
It kind of sucks that the only thing I want with 2h is just Rally.
