My original plan was to have two badge characters--one blueside and one redside. However, I wound up falling in love with a vigilante character, and I've run several Strike Forces with her, leaving me with a pretty good starting list for redside badges. So, my question is this: Is it better to split up the badges and have characters who specialize on either blue or red badges, or should I have my current hero badger eventually go vigilante and collect up the villain badges in addition to the hero badges?
