TLDR: Went gnome (favorite race on Alliance) and thought it wouldn't be an issue because I knew my stuff from Cataclysm. Coming back years later, things feel so different on my DK, and I feel most of the time before I even think of using escape artist for any practical reason there's no need or I'm dead. I feel horrible now and wonder if that DPS difference makes that huge of a difference in addition to skipping over a keybind. People in my guild question why I play a gnome over a human on a death knight in this day and age, claiming it's for warriors mainly. I see Draenei DKs occupying the top ladder now as well for some mystical reason if someone can clarify on that.
