Unlimited free xp. : City of Heroes - Submissions

Very rarely you'll get a mission where you're supposed to retrieve an set amount of objects. These being maybe 5 drug caches or 4 artifacts something like that. In most cases these objects do not give xp when you grab them, but sometimes they DO. If you find a mission like this and you happen to have stealth on your character, you can exploit these missions by running through and grabbing the objects (except ONE, or just whatever you do don't complete the mission) and then exit the mission and logout/login and repeat. This is a very easy way to get hundreds of xp for no work.
