Well I never thought Id say it, but this game could really use tactical LOS.  I was never interested in it personally.... but after playing with the new Battlegrounds DLC, some of the tactical maps are really nice, some interesting layouts..... except that there some walls and other barriers that archers can shoot straight through.  

It just seems a bit silly, but beside that.... the maps are so cool, if you just had the some of the walls etc blocking LOS for archers (and missile type spells) it would really add something to tactical combat.  Yes yes I know, it's a strategically focus game not tactical (which is great imo) but just this one thing would be a great I think. 

It'd open up some cool map possibilities for city battles too.

For 2.0 maybe?
