I still remember the day of seeing the release notes for Threat of Thassarian and start getting levelling my one-hand weapon skills by killing demons in Blasted Lands, and I remember the day when Might of the Frozen wastes trapped the spec into being the two-button spec as due to its more bursty nature, every FotM *snip* flooded the arena and caused the Obliterate to be rendered into a joke and once Blizzard was trying to remedy things I had already re-rerolled to WW Monk which they ended up crippling in the same expansion it got released, so I went enhancement shaman and don't care any more.
If it rocks your boat, have it but for me 2H frost probably was the worst thing to happen to DKs after Blood dps getting shelved along with ArPen's removal.
