A big disappointment after I led Ulfrik and the guys to victory in Solitude, they tell me there are still Imperial camps scattered around the lands, and tell me wipe them out. Sounded cool enough, sure. But, turns out, they all (at least the ones I have now visited) have an unkillable Legate character in them. You can just kill everyone else, and bash him all you want, but he just keeps getting up. What a bummer. I would have preferred if you really were to go and wipe them out, and the camps would be empty after that. At least change the unkillable chracters to killable one.

I know exactly what you mean. When you side with the Stormcloaks the Imperial Legates should realistically lose their essential flags because you know, you didn't join the Legion. I'd classify it as a minor bug.

Yeah, same happens if u side with imperials, Stormocloack's commanders remain immortal
