Support, but only if default movement is 1 (i.e., w/o Speed/Morale promotions) You're right, this bug/feature does cause the AI to attack more poorly. But revolting units already have a lot of advantages, so I like that they don't seem to ever use their trebuchets etc when they get them (the action I usually see is the AI driving the siege units 1 or more tiles away from my cities, possibly because of the ballista turrets, while attacking with the regular land units). If this is fixed, I'm going to get hurt really bad by those rebels. Since units represent multiple fighters & missiles, I don't see an issue with a part of the fighter unit surviving. But I support there being a chance of a complete kill.
