Yeah I think my #1 priority tweak for Civ 5 would be to have somewhere -- cities, forts, anything -- where stacks were allowed for 'storage'. It's such a pain finding somewhere to put your troops when you're not at war: cities and choke points make sense from a strategic point of view, but leads to traffic jams, but even if you can find an "out of the way" spot it means longer marches when the fighting begins.
