"- Improved companion/henchmen AI and gave them the ability to move ahead (using the "Attack" command.)"
One of my favorite improvements I've seen in a long time!
Mostly effects factions with controllable NPCs, however current usages I've found are
-Allows for significantly easier placement of Guards, no more outskirts shuffle (or at least, less of it)
-Once moving through a door, you can order them to move forward, preventing either you or the NPC from being trapped behind it
-For Pack oxen, will make crossing bridges significantly easier
-Obvious RP benefits of scouting, formations, etc.
-If you're patient enough you can even have them walk along side you! -Just need to click attack nearest every 5 seconds or so.
