One of my pet gripes with EU, that I know has been mentioned in threads on other forums, is the use of small suicide armies to halt the movement of a big army. I would have liked this problem to be removed from EU, but PLEASE remove it from EU2. It is especially a problem in South America, where the Incas can hold up an advance for years, despite having virtually no army.
Maybe a moving army could retain all the movement that it had done prior to a battle, but take a bit of time to start moving again. This would mean that the suicide armies could slow down a bigger forces (as a small army harrying a big one might do), but not bring it to a complete halt.
Another possible solution would be to have a skirmish phase of a battle before the main battle and only if an army can survive this without breaking and running can real battle (with the loss of movement) take place.
