Apologies if this has been raised before, I don't get alot of time to visit these boards.
Playing as the Julii and defending on a Stone wall or anything larger, I find that my troops on the wall itself are prone to , well, just to run off and either start decending via the tower or climbing down the ladder. The only way I seem to have any control over them at all is to click a the point on the wall which I need them to defend and hit the halt button when they get close to it. I can never hold them there in an organised formation. It's always in a rough peltast sort of mixed up formation. Extremely annoying when i'm defending a city which is attacked on 3 fronts, as i'm costantly having to keep the camera moving to check that none of my units has started to run away. Anyone have/had this problem?
