Just a wild idea: add the stealth mode on the map and the ability to set ambushes for other parties.
Movement in stealth mode should be considerably slower but the party will be less likely to be seen by others. Vaegir, swadian and manhunter faction units might pay extra attention to stealthing units and become suspicious.
Standing in stealth mode will prepare an ambush. The longer a party is sitting in an ambush, the more effective it becomes. When the party starts moving from an ambush, other parties will not be able to detect it for some time. When an ambush is successful, the ambushing party should get a considerable boost to tactical advantage in the first round of the battle.
Of course non-player parties might use the ambush tactics too, especially against player.
Success of an ambush can be made dependent on some game skill. Tracking is the prime candidate since it doesn't seem to be very useful at present moment (at least as far as I can tell).
