Interesting. To me those are the sort of additions/changes I'd have no problem with, unless (and this is a big one) they overturned precedent already established within an ongoing campaign. If you're saying this was the case, that the changes were made on the fly and broke precedent, then you've a very solid argument against those changes and IMO the DM was in the wrong.@Lanefan, I have some mild resentment about the LotR films when it comes to D&D. I started playing D&D in 3e around the time that LotR was released, and the DM was increasingly "infecting" the first D&D campaign that I played with LotR. Elves started walking on snow when they couldn't before. Wargs went from monstrous wolves to monstrous hyenas. So the intersection of these two things are a bit triggering for me. It's almost a miracle that I didn't quit D&D all together.
That said, I have to assume your DM had never read the LotR books, as Elves being able to walk on snow was a frequently-houseruled thing long before the movies came out.

As for the Wargs, IMO the difference between a monstrous wolf and a monstrous hyena is pretty minor to begin with; and making Wargs into big hyenas allows the Dire Wolf (which in my eyes is a different creature, more like the Starks' wolves in Game of Thrones) to fill the big-wolf niche. This to me is a good change.
