I have very few issues when doing the puzzles with my Warlock. My Hunter is a different story. Not sure I've ever made it to the first enemy area for the Whisper on my Hunter (and I've tried it a few times). Only tried it on my Titan once so I don't really count his attempt. My Warlock is the one who got me A Thousand Wings though. For the ascendant challenges I run the Warlock first and have very few issues with the jumps. I'm getting better with the Hunter, but he still gets tripped up some.
