I was comparing how I was post patch then after 4.2.
My damage in-take improved a bit + the new few pieces ive picked up added to this.
My DPS before patch was around 13-15k in dungeons and I'm still hovering around there, maybe higher depending on group and how well im playing that particular day.
I havent really raided enough post 4.2 to see how it is. I know in trash runs I was pulling 18-20kDPS.
