Not really, no, it didn't destroy the Traviss mandos. At least not yet. (But some of us might be hoping...) And I don't think the RCs will show up much of anywhere. We have Rex, Cody and the 501st to handle that. What's going to be VERY interesting is how they react to the mandos. So far, we've only seen them escorting Anakin with no dialog. That could be the big break point for the Traviss mandos.
