Gotta say those abilities look neat. Don't know if they'll be good, but the way the ball turns when you grapple hook a corner and shit, that's stuff you usually wouldn't see in a FPS(or in most games really besides like Just Cause). Combined with the new Symetra teleports I guess you'll be able to bomb the fuck out of people too.
This shit's gonna be on PTR forever though and then it won't be in OWL until the next season after it's released, so since I don't play the game anymore, not too interesting for a long time.
