I like these changes a lot! Sometimes I can be a little iffy with HC changes cause its always like "Ehhh changing the game from how it used to be" but these are all super beneficial and answers a minor complaint I had since live in regards to the jet pack powers and such. It really makes you wanna pick the travel powers.
The only thing I'd change, and it is a SUPER minor thing I know but its a suggestion at least: I feel like Concealment should have something "Invisiblity" related. Its a superhero game and I feel there should be a power called Invisibility in a game with superpowers. Invisibility is one of the major superpowers always referred to. If anything I'd call Stealth Invisbility and Infiltration Stealth. Or maybe even rename the Concealment power set to Invisibility? Also what appearance will the new Stealth have? The stealth appearance or Invisbility one? Since they're slightly different in transparency? Again relatively minor but it would be nice to have something called Invisibility in a superhero game.
