One of the biggest issues after completing the Civil War is you really can't do anything else. I just worked all the way to top, gained that high rank, just to be able do absolutely nothing that a high ranking soldier should be able to do. Basically Skyrim could use an Assassins Creed Brotherhood type system.
*Rebellions*
-Allow me to send NPC soldiers to take care of any rebellions that may occur after a civil war through a map type feature.
-Allow me to spend gold customizing there gear, choosing if they are light, medium, or heavy armor users and how many to send.
-Allow those NPC soldiers to gain experience if they survive to become better soldiers & allow me to choose where that experience is spent.
-Allow me to recruit soldiers as followers.
-Allow me to lead the attack on the rebellion if I so choose.
-Allow for special quest that can be completed with following soldiers.
-Allow to command a fort, and possibly be given special abilities around that. (Idea by: DeanG)
Any other ideas? What do you think? Any micro-management added to Skyrim would be good IMO.
