The ability to leap tall buildings in a single bound! Not quite, but close. This has a very super feel to it, but there are some problems. If you land somewhere lower than where you took off, you can take serious fall damage. This is a pretty major problem. Also, there is not currently an auto-jump option like there was in City of Heroes, and you cannot even hold down the space bar to keep jumping. This makes using superjump as your primary travel power a bit of a pain.
Advantage of Note: Rebounding Resilience
This advantage makes it harder for holds to land on you. This is pretty nice since there is virtually zero status protection Champions Online (something that desperately needs to be addressed).
NOTE: Readers, if you know of a way to turn this on auto, please post in the comments.
