Oh, and it's definitely great for Caelum, Jotunheim, and Ermor. Although this may be somewhat mitigated now that there's only partial resistances.

There are not only partial resistances, just that the spells affecting the entire battlefield only offer partial resistance. As long as you are not besieging there are domes, but when you siege this is not an option. One way to deal with this is to take out the opposing mage casting the murdering winter. After he has used murdering winter you can target him with veangeance of the dead for example.
