I'm sorry i've got a few questions and hope not to ramble.

Is it viable for Duel Wield Frost to attempt for more haste/hit than is let on from your site stat weight?
From personal experience at the begining of the expansion when I stacked Haste>Crit as DW, I was pulling a few K more than I am now although i'm much more geared.
Can [KM] proc due to off hand?
Does haste>crit help the procs since Frost already has multiple auto-crit procs?
Thank you,
