Just a video of me talking a bit about reverse rolls. I know this tech has been discovered long time ago, this video is just my own take on it. So to do the reverse roll, here is the instruction (PS4 only):
1. Start backpedal (i.e. lock on and move backwards)
2. Press triangle ( to switch from one handed to two handed)
3. Press circle button and almost the same time (or a bit later), click R3 to unlock.
The timing is very strict, and it will take some training to pull off. Also, it doesn't seem to work if you start unlocked. Anyway, you will need to be lock on to backpedal. (Some PVP starts at 13:38 to show case the reverse rolls)
