Oh yes. Well I will decrease rebel garissons mostly (generally might transfer some of the starting regions to players) so that they are possible to get with the smaller sizes of armies that we will have
Well, dungeons faction will probably stay, but you can receive the dungeon missions only if you own the dungeon region. I have there a script for HS that transfers it but I found that its actually not secure enough for a HS, so will check if there is other way to do it or not. Without the missions, there is not much point taking it (except random artifacts)... the dungeon faction is completely frozen, so they are not gonna be a problem. I could also just remove them, will see (the names of the forts also cant be displayed in a HS). Regardles, fort battles are impossible to resolve via online battles anyway (the tool cant do it)
Battle will be limited simply by forbiding to enter it (could just do it via script, but kinda unnecessary)
