What I've found is that it's easy to do the first clip (with the rocket) if you bring up the weapon wheel, but the "pothole" section is annoying to clip with. I keep hearing the falling sound plus a few impact sounds scattered in between, and it seems more like a 10% chance for me. I guess I just need to practise.

I noticed in Azarah's 7-4 runs that they somehow clipped out of the entrance hallway. I've tried it but keep getting stuck in the floor. Has it been patched? If not, how would I go about doing it?
