I was interested in playing with some of my friends the original campaign maps, but instead of coop, 1v1. I am aware that this may not be possible with all of the maps, but for example, for the human campaign where arthas must defend the base for 30min or so, a version of the map where another player can be controlling the undead map and his objective is to destroy arthas base in less than 30 min. Just an example. Anything of the sorts?
