Really interested in what the interface for the mission creation tool will include.
There are a lot of factors in getting certain mobs to either patrol, ambush, guard or other functions in reaction to teams within the mission. Then tie this in a series of missions within a story arc.
There will have to be a very detailed interface to get it right the first time or ways to "test" the mission and tweek it prior to getting the final product.
Overall I give this announcment 3 thumbs up. (Ok so one of the thumbs is a graphic bug.)
