I haven't followed Frost DK too closely of late, but it could easily be that 2h frost was radically outpacing DW, and they wanted to balance between the two, with the particular change to Might of The Frozen Wastes, since a 2h DK deals less damage with any individual Obliterate than a DW would. A theoretical balance between the two sides of the spec seems totally legit.

However, for the broader Obliterate nerfs, yeah, they need to just implement a line in the specialisation benefits of some trees that says "Reduces damage to players and player pets by x%."

The funny thing is DW has been ahead of 2H for a little while now, and only by a small percent. So I don't know what the nerfs are for. Are they trying to get more people to DW for some reason? Are they trying to make unholy the 2h spec of choice? It's anyone's guess. The only thing that makes sense is pvp balance, and even that doesn't make sense, because like I said, DKs aren't killing the charts right now. I don't need DKs of any spec to be OP, I just wish they would leave us be until we actually need to be balanced. Blizzard has to come up with another solution for balancing pvp, period. I think my QQ is legit.

Agreed. I'm tired of the constant class changes because of PVP whining. Split it off into a separate spec entirely, please. Then leave us the frick alone.
