Oh, I agree, the Badge is not earth shaking, though it could be pretty handy in certain situations. The real interesting part is some of the other items that similarly have relatively low level versions with some quite nasty properties or powers. A lot of them don't really depend on their enchantment bonus to make them useful and thus it seems to me there are quite a few that will end up in high level character's "golf bags".
A character that is built for charging and gets big damage increases, while being unstoppable by defenders? Sounds potentially Earth shattering to me. We had a Rogue in our party that had several items that added to charging damage. When combined with that badge and sneak attack damage I could see him pushing 80+ points a round, at pre-Paragon levels and without taking hits in return.
